A triangle has interior angle measurements of 5s, 3s - 9 degrees, and 45 degrees. What is the value of s?

s = 18

Step-by-step explanation:

A triangle's interior angles must all add up to 180 degrees.

Since you know 1 angle is 45 degrees, then the last 2 angles must equal 135 degrees.

Write the equation based on the you were told about the other 2 angles:

5s +  ( 3s - 9) = 135

Solve for s:

5s + 3s - 9 = 135

Add the like variables and add 9 to both sides of the equation.

8s = 144

Divide both sides by 8

s = 18

Angle 1 = 5s = 5 x 18 = 90

Angle 2 = 3s - 9 = 3(18) - 9 = 54 - 9 = 45

step-by-step explanation:

location: point 0

step-by-step explanation:

well, -8 to 10 on a number line is 18 spaces.

1/9 of 18 is 2.

so, 4/9 of 18 must be 8.

8 spaces from -8 (a) is 0.

so, 4/9 of the way from -8 to 10 is 0!
