Write equation and solve for value of X (2 questions)
Fairly simple I just can’t seem to remember for finals thank you!

31) x = 25 degrees

Equation: (2x+15) + x + 90 = 180 degrees

--> 3x+105 = 180

> 3x = 75

> x = 25 degrees

32) x = 17 degrees

Equation: (x+52) + (3x+21) + 39 = 180 degrees

--> 4x+112 = 180

> 4x = 68

> x = 17 degrees

11

step-by-step explanation:

32.50-7.50=25

225/25=11

answer:   b

step-by-step explanation:

x2 = 16

x can not be a negative number because 16 is positive

the only answer would be positive 8
