Answer: p>300
Step-by-step explanation:
Answer:
1/2 + 10/12. = 1/2 × 6/6 =6/12. 6/12 + 10/12 =16/12. 16/12 = 1 4/12 = 1 1/3
b ≈ 7.8
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 )
