Question

The hypotenuse of right triangle ABC, line segment AC, measures 13 cm. The length of line segment BC is 5 cm. What is the approximate difference between m

Answer 1

B) 44.8

Explanation:

cos ( ∠C ) = 5/13 = 0.38462

m ∠C = cos^(-1) 0.38642 = 67.4°

m ∠A = 90° - 67.4° = 22.6°

m ∠C - m ∠A = 67.4° - 22.6° = 44.8°
