Question

help please

Answer 1

The interior angles of a rectangle are all right angles.
Right angles have a measure of 90.

Therefore, (1/3)*x + 8 = 90

Answer 2

(1/3)*x + 8 = 90

Multiply each member of the equation by 3.

3 * (1/3)*x +3* 8 = 3*90

x + 24 = 270 -->

@aprilann143 Your turn: Solve for x. Post what you get and we can compare answers, okay? Note how the fractions were eliminated.

Answer 3

@aprilann143 This is what you are solving for x:

x + 24 = 270
