x+2 = 30
x = 28
The correct answer is C
Answer:
Step-by-step explanation:
surface area=4πr²=36π
r²=9
r=3
sin(0) = opposite/hypotenuse = 2/5
cos(0) = adjacent/hypotenuse = sqrt21/5
tan(0) = opposite/adjacent = 2/sqrt21 * sqrt21/sqrt21 = 2sqrt21/21
cot(0) = adjacent/opposite = sqrt21/2
sec(0) = hypotenuse/adjacent = 5sqrt21/21
