what is the value of m 1 to be if 1 and 2 are complementary angles and m 2 =85 degree
Complementary angles are two angles whose measures add up to 90 degrees.
Given that angle 1 and angle 2 are complementary angles, and angle 2 is 85 degrees, we can find the measure of angle 1 by subtracting angle 2's measure from 90.
So, if angle 2 is 85 degrees,
angle 1 = 90 degrees - 85 degrees = 5 degrees.
Therefore, the value of angle 1 is 5 degrees.
