Question

Angles A and B are supplementary. Angle A measures (2x + 20).Angle B measures 130 degrees. Solve for X​

Answer 1

x = 15

Explanation:

Supplementary = 180 °

Add the numbers

`(2x + 20) + 130 = 180`

`2x + 150 = 180`

Subtract 150 from both sides of the equation

`2x+150- 150 =180 - 150`

Simplify

`2x = 30`

Divide both sides of the equation by the same term

`(2x)/(2) =(30)/(2)`

Simplify/Solution =

`x=15`

Hence, x = 15.
