A convex polygon has 4 sides what is the sum of the measure of its interior angles? Help me please!!!

360 degrees

Step-by-step explanation:

Use the equation for finding the interior angle sum

sum = (n - 2)x 180, where n is the number of sides

sum = (4 - 2)x 180

sum = 2 x 180

sum = 360

The sum of interior angles for a four-sided figure is always 360 degrees.

If this answer is correct, please make me Brainliest!

Step-by-step explanation:

Theorem 39: If a convex polygon has n sides, then its interior angle sum is given by the following equation: S = ( n −2) × 180°. ... Theorem 40: If a polygon is convex, then the sum of the degree measures of the exterior angles, one at each vertex, is 360°.

$25

step-by-step explanation:

25 - 4.50 = 20.5

20.5 / 2 = 10.25

10.25 + 10 = 20.25

20.25 - 12.50 = 7.75

therefore the answer is $25 as shown as the first number.
