Question

can someone help me with this problem, please? Solve the triangle. Round decimal answers to the nearest tenth.

Answer 1

A is about 37.6 degrees

B is about 38.4 degrees

a is about 15.7 units

Explanation:

Using the law of sines, you know that:

`(\sin 104)/(25)=(\sin B)/(16)`

`B\approx 38.4^(\circ)`

Since all of the angles of a triangle add up to 180 degrees, angle A must be 180-104-38.4=37.6 degrees.

Finally, for side a:

`(\sin 104)/(25)=(\sin 37.6)/(a)`

`a\approx 15.7`

Hope this helps!
