Answer: 163/27
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
3x + -1/9 = 18
Step 2: Add 1/9 to both sides.
3x + -1/9 + 1/9 + = 18 + 1/9
3x = 163/9
Step 3: Divide both sides by 3.
3x/3 = 163/9 over 3
x = 163/27
Answer: Measure angle H = 42°
Step-by-step explanation:
"In a triangle, the measure of the exterior angle is equal to the sum of the measures of the two non-adjacent angles to the exterior angle"
In given we have,
angle E is an exterior angle to triangle DFH
The two non-adjacent angles to angle E are angles D and H
Based on the above rule,
measure angle E = measure angle D + measure angle H
We are given this:
angle E = 87°
angle D = 45°
Substitute with the givens in the above rule and solve for the measure of angle H as follows:
angle E = angle D + angle H
87° = 45° + measure angle H
measure angle H = 87° - 45°
measure angle H = 42°
