Answer:
Step-by-step explanation:
The opposing side and the hypotenuse for the angle are given.
Remember, when the opposing side and the hypotenuse are given, take the cos ratio.
(f+g)(x) = f(x) + g(x)
= 2x² + 1 + x² - 7
= 3x² - 6
I'm pretty sure it's the first one
Area of semicircle =( π r2)÷ 2
= 1/2 × 22/7 × 11 ×11
= 11 × 17.5
= 19.25 CM2
11/15
