Question

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

Answer 1

Answer:

x = 15

Step-by-step explanation:

(2x + 20) + 130 = 180

2x + 150 = 180

     - 150   - 150

2x = 30

/2     /2

x = 15

Answer 2

Answer:

x = 15

Step-by-step 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

$\frac{2x}{2} =\frac{30}{2}$

Simplify/Solution =

$x=15$

Hence, x = 15.
