Question

The measure of exterior angles of a pentagon are 3x - 15° , x + 15° , 2x + 2° , 3x and 3x - 2° .

Answer 1

Answer:

the sum of exterior angles is sane as that of interior that is 540°

$3x - 15 + x + 15 + 2x + 2 + 3x + 3x - 2 = 540 \\ 12x + 0 = 540 \\ x = \frac{540}{12} \\ x = 45$

Answer 2

Answer:

Sal demonstrates how the the sum of the exterior angles of a convex polygon is 360 degrees.
