Is Anyone know the answer?

Angle 1 = 40

Step-by-step explanation:

Angle 1 and Angle 2 are alternate angles. So,

2x + 20 = 3x + 10

3x - 2x = 20 - 10

x = 10

Angle 1 = 2x + 20 = 2 x 10 + 20 = 40

∠1 = 10°

Step-by-step explanation:

                           ∠1 = ∠2

                  2x + 20 = 3x + 10

2x + 20 + (-3x - 20) = 3x + 10 + (-3x - 20)

                            -x = -10

                             x = 10

the answer would be 1 1/72

step-by-step explanation:

you can rewrite the equation by separating the parts and then solving individually:

10-9=1

1/8 - 1/9=

find l c d and then combine:

1 1/72
