Find the measure of the third side. Do not use a calculator.

Question

1. a = 6, b = 8, γ = 60°
2. a = 15, c = 22, β = 135°

Solve the triangle. Round answers to the nearest tenth. (No digram given)

1. b = 3.4, c = 2.8, α = 82°
2. a = 11.2, b = 15.3, γ = 116.4°

Answer 1

2 for 6,8,60 degrees 3rd side = 2sqr13 or about 9.08, 2 triangles possible

for 15, 22, 135 3rd side = about 34.29 or 8.67

for 3.4, 2.8 and 82 3rd side = about 4.1 or 2.4

for 11.2, 15.3 and 116.4 3rd side = about 22.6 or 6.6

each of the four have two possible triangles
