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 )
A. A= 4
b. b= 5.6
c. c=4
d. e= 3.2

Answer:
C
Step-by-step explanation:
a=r^2
To find the radius, divide the diameter by 2
r=d/2
r=10/2
r=5
a=r^2
a=5^2
a=25
So, choice C is correct
