Question

Use the information to solve the triangle. Round your answers to two decimal places. Hint: draw a sketch first to determine if you should use Law of Sines or Cosines.

B=104°, C=33°, a=18.1

Answer 1

A = 43°

b = 25.8 (3 sig. fig.)

c = 14.5 (3 sig. fig.)

Explanation:

Using angle sum of triangle, we get A = 180 - 104 - 33 = 43°

Using sin law,

b/sin104 = 18.1/sin43

b = 25.8 (3 sig. fig.)

c/sin33 = 18.1/sin43

c = 14.5 (3 sig. fig.)
