Answer 1

64.2

Explanation:

Find the last side of the triangle using the Pythagorean theorem.

Solve the equation for c.

c=√1037

Find B.

The angle B can be found using the inverse sine function.

Substitute in the values of the opposite side to angle

B and hypotenuse √1037 of the triangle.

B=arcsin(29/√1037)

B=64.23067237
