Question

I need someone to solve for the variable and show how plzz

Answer 1

Answer:

Step-by-step explanation:

2(x + 15)⁰ + (3x + 20)⁰=180⁰

2x + 30⁰ + 3x + 20⁰=180⁰

2x + 3x + 30⁰ + 20⁰=180⁰

5x + 50⁰ - 50⁰=180⁰-50⁰

5x=130⁰

5x/5=130⁰/5

x=26⁰

Answer 2

Answer:

x should equal 26.

Step-by-step explanation:

since they are cointerior angles:

2 (x + 15) + (3x + 20) = 180

2 (x) + 2 (15) + (3x + 20) = 180

2x + 30 + (3x + 20) = 180

2x + 30 + 3x + 20 = 180

5x + 50 = 180

5x + 50 - 50 = 180 - 50

5x = 130

5 ÷ 5x = 130 ÷ 5

x = 26
