The answer is (A) 135.
<em>
REMINDER: Interior angles are equal.</em>

Each interior angle = 180 - $\frac{360}{No.OfSides}$
Each Interior angle = 180 - $\frac{360}{8}$
Each Interior angle = 180 ° - 45°
= 135°

EACH interior angle = 180 - (360 / # of sides)
EACH interior angle = 180 - (360/8)
EACH interior angle = 180 -45
EACH interior angle = 135

Steven and Gina each wrote an expression, but only Steven’s expression is equivalent to 4x - 8. What could be Gina’s expression?

2(2x-4) because when you multiply 2 x 2x it equals 4x. When you multiply 2 x 4 it equals 8. Leaving you with 4x-8

The length of the hypothenuse or the value of x is equal to 19.53

Data;

hypothenuse = x
adjacent = 11.2
opposite = 16

<h3>Pythagoras's Theorem</h3>

To solve this problem, we have to use Pythagoras's theorem which is used to find the missing side in a right angle triangle if we have at least two sides.

The formula for this is

$x^2 = y^2 + z^2\\$
