This question seems to be incomplete but I have already encountered and answered this problem.
To complete the question:
The hypotenuse of right triangle ABC, line segment AC measures 13 cm. The length of line segment BC is 5cm.
What is the approximate difference between m ∠C and m∠A?
34.8
44.8
46.3
47.9
To solve:
cos (∠C) = 5/13
=0.38462
m∠C = cos^(-1) 0.38642
=67.4 degrees
m∠A = 90 degrees - 67.4 degrees
=22.6 degrees
m ∠ C - m∠A
=67.4 - 22.6 = 44.8 degrees
The answer is :
44.8 degrees
