Answer:

<em>C) -1(x+8)(x+7)</em>

Step-by-step explanation:

-x^{2} -15x-56\\-1(x^{2} +15x+56)\\-1(x+8)(x+7)

-1 factors through the entire equation.

8+ 7 = 15 and 8 x 7 = 56 (so 8 and 7 are our factors.)

M 2 = 2x°, m 3 = 5x°, m 1 =<br><br> 2x + 5x<br> 5x - 2x<br> 180 - 5x<br> 180 - 7x
MaRussiya [10]

We know: the sum of measures of triangle angles is 180°.

Therefore we have the equation

m\angle1+m\angle2+m\angle3=180^o\to m\angle1=180^o-m\angle2-m\angle3

Substitute m\angle2=2x,\ m\angle3=5x:

m\angle1=180-2x-5x=180-7x

<h3>Answer: 180 - 7x</h3>
