Question

In this triangle, which of the following is true?

A. The measure of x is 55° and a = 11.47
B. The measure of x is 55° and a = 11.40
C. The measure of x is 22° and a = 11.47
D. The measure of x is 55° and a = 16.38

Answer 1

a = height and height = hypotenuse* sin (35) = 20* 0.5735 =11.47
sum of angles =180 , x + 35 +90 = 180, x= 55
