X=[(x+60°)-20°]/2
x=(x+60°-20°)/2
x=(x+40°)/2
Solving for x: Multiplying both sides of the equation bu 2:
2x=2(x+40°)/2
2x=x+40°
Subtracting x both sides of the equation:
2x-x=x+40°-x
x=40°
Answer: x=40°

Answer:
The radius will change from 0.977 feet to 1.49 feet.
Step-by-step explanation:
The area of a circle with radius r is given by πr².
If the are of the circle is 3 square feet, then πr² = 3, ⇒ r²=
⇒ r² =0.9545, ⇒ r=0.977 feet.
If the area of the circle changes to 7 square feet, then its radius will change to r²= =2.228, ⇒ r =1.49 feet.
Therefore, the radius will change from 0.977 feet to 1.49 feet. (Answer)
