Answer:
x = 60.
Step-by-step explanation:
Vertical angles are congruent so
x + 20 = 80
x = 80 - 20 = 60.

Answer:
6in
Step-by-step explanation:
The volume of a spherical balloon is 4/3 π R^3.
So 288π = 4/3 π R^3
The factors of π cancel out. Divide both sides by 4/3 to get:
216 cubic inches = R^3
Take the cube root of both sides, and you find that R = 6 inches
Answer:
117 degrees
Step-by-step explanation:
Two vertical angles will always equal each other.
So, set up an equation where angle A and angle B equal each other to solve for x:
5x - 3 = 4x + 21
5x = 4x + 24
x = 24
Plug in 24 for x in the expression represent angle A:
5(24) - 3
120 - 3
117
