Question

Use the right triangle and the given information to solve the right triangle.

b=3, B=31° ; find a, c, and A

Answer 1

a= 4.993

c = 5.824

A= 59°

C = 90°

Explanation:

b=3, B=31°

Since it's a right angle.

C = 90°

A = 180-90-31

A= 59°

For side a and c

a/sin A = b /sin B

a = sinA * b/sin B

a= sin 59 * 3/sin31

a= 4.993

a = 5

c/sin C = b/sin B

c = sin C * b/sin B

c = sin90 * 3/sin 31

c = 1* 5.824

c = 5.824
