Find m∠BAC in the figure shown below.
Line upper D upper C is shown intersecting with line upper E upper B at point upper A. The angle upper E upper A upper D is labeled 80 degrees.
A. m∠BAC=80°
B. m∠BAC=100°
C. m∠BAC=10°
D. m∠BAC=50°
Since angle ABC and angle ABD are supplementary (they form a straight line), we can find m∠ABC by subtracting 80° (given angle) from 180° (sum of angles in triangle ABD).
m∠ABC = 180° - 80° = 100°
Similarly, angles ABC and BAC are supplementary, so:
m∠BAC = 180° - m∠ABC = 180° - 100° = 80°
Therefore, the answer is A. m∠BAC=80°.
An angle measures 47°. What are the measures of the angle’s complement?
A. 43°
B. 133°
C. 53°
D. 143°
Since the complement of an angle is the angle that when added to it results in a sum of 90°, we can find the measure of the complement of 47° by subtracting 47 from 90:
90° - 47° = 43°
Therefore, the answer is A. 43°.
Which of the following correctly identifies angles that add up to 90° and 180°?
A. adjacent angles, congruent angles
B. complementary angles, vertical angles
C. supplementary angles, complementary angles
D. vertical angles, adjacent angles
B. complementary angles, vertical angles.
Complementary angles add up to 90° and are angles that complement each other, while vertical angles are opposite to each other and have the same measure.
Identify the correct ways to classify ∠1 and ∠4 in the figure shown below.
A horizontal line is intersected at a right angle at the endpoint of a ray pointing up. Another line goes through the intersection point from upper left to lower right. Angle 1 is left of this line and right of the ray. Angle 2 is left or ray and above horizontal line. Angle 5 is below horizontal line and right of slanted line. Angle 3 is right of slanted line and below horizontal line. Angle 4 is above horizontal line and left of slanted line.
A. adjacent, supplementary
B. adjacent, complementary
C. adjacent, congruent
D. vertical, complementary
A. adjacent, supplementary.
Angles 1 and 2 are adjacent because they share a common vertex and a common side, and angles 3 and 4 are adjacent for the same reasons.
Angles 1 and 2 form a straight line, so they are supplementary (add up to 180°), and angles 3 and 4 also form a straight line and are therefore supplementary.
Therefore, the correct classification is adjacent, supplementary for both angles 1 and 4.
Which of the following statements about special angle relationships is not correct?
A. It is possible for angles to be both vertical and complementary.
B. It is possible for an obtuse angle to have both a complement and a supplement.
C. It is possible for an acute angle to have both a complement and a supplement.
D. It is possible for angles to be both congruent and supplementary.
A. It is not possible for angles to be both vertical and complementary.
Vertical angles are opposite to each other and have the same measure, while complementary angles add up to 90°. Since vertical angles are never adjacent, they cannot be complementary.
Therefore, the statement "It is possible for angles to be both vertical and complementary" is not correct.
gimmie the types of triangles bot
Here are the six types of triangles:
1. Equilateral: All three sides are equal in length, and all three angles are equal to 60 degrees.
2. Isosceles: Two sides are equal in length, and two angles are equal in measure.
3. Scalene: None of the sides are equal in length, and none of the angles are equal in measure.
4. Right: One of the angles is a right angle (90 degrees).
5. Acute: All three angles are acute (less than 90 degrees).
6. Obtuse: One of the angles is obtuse (greater than 90 degrees).
A classmate believes that a triangle can have both a right angle and an obtuse angle. Which of the following statements would you use to convince him that he is incorrect?
A. It is not possible because the sum of the angles in the triangle can’t exceed 180°.
B. It is not possible because if a triangle has an obtuse triangle, that means all the angles are obtuse angles.
C. It is not possible because if a triangle has a right triangle, that means all the angles are right angles.
D. It is possible. The classmate is correct.
B. It is not possible because if a triangle has an obtuse triangle, that means all the angles are obtuse angles.
An obtuse angle is an angle that measures greater than 90 degrees, and a right angle measures exactly 90 degrees. Since the sum of the angles in a triangle is always 180 degrees, it is impossible for a triangle to have both an obtuse angle (greater than 90 degrees) and a right angle (equal to 90 degrees), because that would mean the third angle would have to be negative or non-existent.
Therefore, statement B would be the best way to convince the classmate that they are incorrect.
How does this image show a unique quality of Byzantine culture?
A.
The mosaic portrays Jesus.
B.
The mosaic uses colorful tiles.
C.
The mosaic is a realistic image.
D.
The mosaic depicts Jesus with a golden halo.
D. The mosaic depicts Jesus with a golden halo.
The portrayal of Jesus with a golden halo in the mosaic represents a unique quality of Byzantine culture that developed its own distinctive artistic style. The use of halos, particularly golden ones, is a recurring feature in Byzantine art and represents the divine radiance of the Holy figures. The prominence given to the golden halo around Jesus in the mosaic indicates the high regard with which the Byzantines held their religious figures and underscored the importance of religious iconography in Byzantine art.
