Answer:

10 = b

Step-by-step explanation:

Begin by expanding (x + 5)^2

(x + 5)(x + 5)

First: x*x = x^2

Outside: x *  5 (the last term which is a 5)

Inside: 5+ x

Last:  5*5 = 25

x^2 + 5x + 5x + 25

x^3 + 10x + 25

Find the value of x and pls explain!!❤❤❤
AlexFokin [52]

Answer:

x = 52 degrees.

Step-by-step explanation:

Here we make use of the fact that the interior angles of any triangle add up to 180 degrees.  Before this we must find an algebraic expression for interior angle RQS:  

Since angle RQS + x + 72 = 180 degrees, angle RQS is equal to 180 -72 - x, or 108 - x.

The sum of the three interior angles is then

108 - x + 90 + 34, or 232 - x degrees, and this sum must equal 180 degrees.

Then 232 - x = 180.  Solving for x, we get x = 52 degrees.
