Solve for x
30=-5(6x+6)

x = -2

Step-by-step explanation:

30=-5(6x+6)

step 1 distribute the -5

-5 * 6x = -30x

-5 * 6 = -30

we now have 30 = -30x - 30

step 2 add 30 to each side

30 + 30 = 60

-30 + 30 cancels out

we now have 60 = -30x

step 3 divide each side by -30

-30x/-30 = x

60 / -30 = -2

we're left with x = -2

3; 9 is 8 to -4

step-by-step explanation:

according to the triangle sum theorem, all the angles in a triangle must add up to 180 degrees. if we know one angle is already 90, we do 180-90=90. the other 2 angles must add up to 90, exactly.
