Answer:
b ≈ 7.8
Step-by-step explanation:
using the law of sines
∠ A = 180° - 105° - 40° = 180° - 145° = 35° , then
= 
( cross- multiply )
b × sin35° = 7 × sin40° ( divide both sides by sin35° )
b = 
≈ 7.8 ( to the nearest tenth )
Answer:
it can be 1/3, 1/7, 2/7, 3/7, 1/5, 2/5, 1/13, 2/13, 3/13, 4/13, etc
22 = z + (-9) Switch the sides
z = 22 - (-9) Solve
z = 31 So, z = 31
Step-by-step explanation:
