Answer:
- 22.5
Step-by-step explanation:
Substitute x = 3 into f(x) and x = 16 into h(x) , then
g(3) - h(16)
=
× - 3(3)² - (2
+ 1)
=
× - 3(9) - (2(4) + 1)
=
× - 27 - (8 + 1)
= - 13.5 - 9
= - 22.5

The two angles are supplementary angles and when added together equal 180 degrees.
3x -12 + x+2 = 180
Simplify:
4x -10 = 180
Add 10 to both sides
4x = 190
Divide both sides by 4
X = 190/4
X = 47.5
