Angle A and Angle B are supplementary, mZA = (6x + 72) and mZB = (2x + 28)". Find x, the
Alexeev081 [22]

Answer:

x = 10

m<A = 132 degrees

m<B = 48 degrees

Step-by-step explanation:

Supplementary = angles that make up 180 degrees

We know <A and <B are supplemntary, so 2x+28+6x+72 = 180.

8x + 100 = 180

8x = 80

x = 10

I input 10 into the equations to solve for the measures of the angles

Please explain how to do this math​
N76 [4]

Answer:

x=9

Step-by-step explanation:

First, distribute the 2 and each value in the parentheses.

2*x+2*5. This is the first half of the equation.

2*x+2*5= 3x+1 You can then simplify

2x+10=3x+1 Subtract 3x from both sides

(2x-3x)+10=(3x-3x[cancels out])+1

-x+10=1 Now subtract 10 from both sides

-x(10-10[cancels out to 0])=(1-10)

-x=-9 Since x is negative we need to solve for positive

x=9
