Question

Solve for an Angle in right triangles

Answer 1

B = 56.25

Explanation:

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

cos theta = adjacent/ hypotenuse

cos B = 5/9

Take the inverse cos of each side

cos ^-1 (cos B) = cos ^-1 (5/9)

B =56.2510114

To the nearest hundredth

B = 56.25
