Answer:

60°

Step-by-step explanation:

Sum of angles of triangle = 180°

x + 40 + 80 = 180

x + 120 = 180 {Subtract 80 from both sides}

x = 180 - 120

x = 60°

If the area of a circle is 58 square feet, find the circumference. A. 42.5 ft. B. 4.25 ft. C. 22.35 ft. D. 26.99 ft.

PSYCHO15rus [73]

Answer: OPTION D.

Step-by-step explanation:

The formula for calculate the circumference of a circle is:

$C=2r\pi$

Where r is the radius.

The formula for calculate the area of a circle is:

$A=r^2\pi$

Where r is the radius.

Solve for r from $A=r^2\pi$ to calculate it:

$r=\sqrt{\frac{A}{\pi}}\\r=\sqrt{\frac{58ft^2}{\pi}}\\r=4.296ft$

Subsitute the radius into $C=2r\pi$ . Then:

$C=(2)(4.296ft)\pi=26.99ft$
