Answer:

x = -1

Step-by-step explanation:

<em>(x + 4)² = 9</em>

Find the square root of both sides so that the square is gone.

<em>√(x + 4)² = √9</em>

<em>x + 4 = ±3</em>

Get x along on one side by subtracting 4 from each side.

<em>(x + 4) - 4 = ±3 - 4</em>

<em>x = -1, -7</em>

RS bisects QRT, mangleQRS = (3x + 8), and mangleSRT = (5x − 4).
Leya [2.2K]

Bisect typically means half but since we aren't given angle at the start so we can just have to solve for x.

(3x + 8) = (5x - 4)

3x = 5x - 12

-2x = -12

x = 6

Best of Luck!
