An angle measures 18° more than the measure of a supplementary angle. what is the measure of each angle?

Step-by-step explanation:

Supplementary angles are 180*

So 180+18= 198*

Supplementary angles are two angles that add up to 180°

The unknown angle is known as x

The second angle, being 18° more than the unknown angle, is x+18

So, the expression can be written as x+x+18=180

Subtract 18 from both sides.

x+x=162

Combine like terms

2x=162

Divide by 2 on both sides

162/2=81

x=81

So, one of the angles is 81°

The other is 99° ( because 81+18)

y < -3

step-by-step explanation:

-3y - 2 > 7

-3y -2 + 2 > 7+2

-3y > 9

-3y/-3 < 9/-3   (change the inequality sign when multiplying or dividing by a negative number)

y < -3
