An angle measures 7/9pi radians. what is the degree measure of the angle?
a. 140°
b. 280°
c. 439.6°

The degree measure of the given angle ⁷/₉π rad is; Option A;  140°.

From conversion of angles in radians to degrees, we know that;

2π rad = 360°

Now, we want to convert ⁷/₉π rad to degree. Thus;

⁷/₉π rad = (⁷/₉π rad × 360)/(2π rad)

⇒ (7 * 360/18)

⇒ 140 °

In conclusion, the degree measure of the given angle ⁷/₉π rad is  140°.
