Question

Find the value of m<3-m<1.
A. 20°
B. 50°
C. 90
D. 120°

Answer 1

B. 50°

Explanation:

70° and m<1 are Complementary Angles, meaning they add up to 90°, so, m<1 is 20°. Now, m<3 is also 70° because they are Alternative Angles, meaning that they are reflexive. Now you can perform your deduction:

70 - 20 = 50
