Sadly no one wants to help
if you look this up
open study name a pair of complementary angles
its the first result
click on it the image is omarios reply
Does anyone have the answers!?
Plz need answers to a few of these
1. To find a pair of complementary angles, we need to identify two angles whose measures add up to 90 degrees. Looking at the figure, we can see that a pair of complementary angles is angle sign1 and angle sign4.
2. To find the measure of angle sign4, we need to know the measure of angle sign1. The question tells us that mangle sign1 = 37°, so angle sign4 would have the same measure as angle sign1. Therefore, the measure of angle sign4 is 37°.
3. Similar to the previous question, if mangle sign1 = 40°, then angle sign5 would have the same measure as angle sign1. Therefore, the measure of angle sign5 is 40°.
4. To identify a pair of alternate interior angles, we need to look for angles that are on opposite sides of the transversal (line JL) and are both inside the parallel lines. From the figure, we can see that a pair of alternate interior angles is angle sign3 and angle sign6.
5. Since angle sign4 and angle sign8 are corresponding angles, their measures would be the same. Therefore, if mangle sign4 = 105°, then the measure of angle sign8 is 105°.
6. Angle signABC is congruent to angle signCAB. Congruent angles have the same measure.
7. Side BC is congruent to side YZ. Congruent sides have the same length.
8. To find EF and mD, we need more information or measurements from the right triangle in the figure. Without additional information, we cannot determine the values of EF and mD.
9. Without knowing the measures of the other two angles in the right triangle, we cannot determine the degree measure of the third angle. The sum of the angles in a triangle is always 180 degrees, so if we know the measure of one angle, we can find the measures of the other two angles by subtracting the known angle from 180 degrees.
10. To translate triangle ABC 2 units right and 4 units down, we need to add 2 to the x-coordinates and subtract 4 from the y-coordinates of the vertices. From the graph, we can see that the new coordinates for point A would be (2, -1).
11. Triangles can be classified by their angles as acute, right, or obtuse. The options provided for question 11 don't mention any specific angles, so it is not possible to determine the correct answer without more information.
12. Without knowing the measurements of the sides and angles of the triangle in the figure, we cannot accurately classify it as scalene, isosceles, equilateral, acute, or obtuse.
13. The quadrilaterals that have four equal sides are a rhombus and a square.
14. The sum of the interior angles of a pentagon is 540 degrees.
15. To find the value of the missing angle, we need to consider that the sum of the interior angles of a triangle is always 180 degrees. From the figure, we can see that the sum of the two angles given is 80 degrees. Therefore, the missing angle would be 100 degrees.
16. To find the area of the triangle, we need to know the lengths of its base and height or the lengths of its sides. Without this information from the figure, we cannot determine the area of the triangle.
17. To find the area of the parallelogram, we need to know the length of its base and height. Without this information from the figure, we cannot determine the area of the parallelogram.
18. Similar to the previous questions, to find the area of the trapezoid, we need to know the lengths of its bases and height. Without this information from the figure, we cannot determine the area of the trapezoid.
19. To identify a sequence of transformations that maps triangle ABC onto triangle A''B''C'', we need to analyze the figure that shows the two triangles. Without the actual figure, it is impossible to determine the correct sequence of transformations.
