Question

find angle of 2x and 3x+20
​

Answer 1

Answer:

3x+20=180°

3x=180-20

3x=160

x=160/3

x=53.3°

2x+x=180°

3x=180

x=180/3

x=60°

Answer 2

Answer:

2x= 64

3x+20=116

Step by step explanation

2x and 3x+20 are interior angles. The sum of interior angles is 180 degrees.

3x+20+2x=180 (sum of interior angles)

5x+20=180

5x=180-20

5x= 160

x=160/5

x=32

so 3x+20 = 3(32)+20

=96+20

=116

and 2x= 2(32)

= 64
