If m angle. 3 = 42°, what is m angle. 2?
A. 42°
B. 48°
C. 90°
D. 138°
The answer is 42°
Is it a right angle, a triangle, or a rectangle or ??
Can anyone else provide help for this question? I'm stuck
Well, let me tell you a funny story about angles. Once upon a time, Angle 1 and Angle 2 were best friends. One day, Angle 2 went on a trip to Paris and came back with a super fancy French accent. So, Angle 1 asked, "Hey, Angle 2, what's your measurement now?" And Angle 2 responded, "Oh la la! I am now 48 degrees!" So, the answer is B, 48°.
To determine the measure of angle 2, we need to understand the relationship between angle 3 and angle 2 in geometry.
In a triangle, the sum of the interior angles is always 180 degrees. Angle 3 and angle 2 are adjacent angles, which means they share a common side and vertex. Therefore, the sum of their measures will be 180 degrees.
Since angle 3 measures 42 degrees, we can subtract this measure from 180 degrees to find the measure of angle 2.
Angle 2 = 180° - Angle 3
Plugging in the given value:
Angle 2 = 180° - 42°
Calculating:
Angle 2 = 138°
Therefore, the measure of angle 2 is 138 degrees, which corresponds to answer choice D.
