1a) Some of the interior angles of a 15-gon must be 13 x 180=2340 degrees. Since it’s regular, the total is shared equally among the interior angles. 2340/15=156 degrees

Answer:

1a) 2340

1b) 120°

Step-by-step explanation:

1a) formula to find the sum of the interior angles is: (n-2) * 180

n = the number of sides

(15-2) * 180

(13) * 180 = 2340

2a) the formula to find the measure of one interior angle is:   \frac{(n-2) * 180}{n}

n = the number of sides

a hexagon has 6 sides

(6-2)*180

4 * 180 = 720

720 ÷ 6 = 120

If zb⊥ya , find m<br><br>A. 28<br><br>B.46<br><br>C.56<br><br>D.62<br><br>I'll give you brainliest
prohojiy [21]
<h3>Answer:</h3>

A. 28

<h3>Step-by-step explanation:</h3>

We assume m is the measure of the marked unknown angles: ∠BZY ≅ ∠BZA

(5x +3)° = (2x +18)°

Divide by ° and subtract 2x+3:

... 3x = 15

... x = 5

Then ∠BZA = (2·5 +18)° = m = 28°
