∠A and \angle B∠B are supplementary angles. If m\angle A=(7x+7)^{\circ}∠A=(7x+7) ∘ and m\angle B=(4x-14)^{\circ}∠B=(4x−14) ∘ , then find the measure of \angle B∠B.

c

Step-by-step explanation:

c is answer

i think it's ф or x=6,-6

step-by-step explanation:

-x^2=-36

x^2=-36

ф

or

if you mean by : -(x^2)=-36

it'll be: x^2=36

x=6,x=-6

hope it'll ! have a good day!

you for asking!
