Thread: Need help solving Multipart Triangle

Hello, I need help solving for all the sides of the large triangle. Can someone tell me how to solve?

Solve for A and B

Angles in a triangle add up to 180 degrees.

therefore the third angle will be 180-14-34 = 132

use the sine rule:

30/sin(132) = B/sin(14)
30sin(14)/sin(132)=B
9.76614 = B


30/sin(132) = A/sin(34)
30sin(34)/sin(132)=A
22.474 = A

Side A = 22.47 (2dp)
Side B = 9.77 (2dp)
