Question

Find measurement of angle CBA

Answer 1

Answer:

B= 70.53

Step-by-step explanation:

Since this is a right triangle, we can use trig functions

cos theta = adj / hypotenuse

cos B = 3/9

Taking the inverse cos of each side

cos^-1 cos B = cos ^-1 (1/3)

B =70.52877937

Rounding to the nearest hundredth

B= 70.53
