Answer:
The answer to your question is: the first option - 9/
Step-by-step explanation:
Process
cosФ = adjacent side / hypotenuse
-1/9 = adjacent side / hypotenuse
adjacent side = -1 hypotenuse = 9
c² = a² + b²
b² = c² - a²
b² = 81 - 1
b = b = opposite side
But b is negative because we are in the third quadrant.
b = -
Finally csc Ф = hypotenuse / opposite side
csc Ф = - 9 /
Answer:
The question does not have value of height (in the image)
the barn in shape of a cuboid with a half cylinder.
volume of barn = volume of cuboid + volume of cylinder/2
here,
b=6 m
l=10 m
so, 2r=6. thus, r=3,
which approximately,
141.3+60h
for storing all of the hay
141.3+60h≥600
h≥7.644
so..
check if h is less than 7.644, he would not be able to store all of the barn.
mark brainliest please.
