Answer:
21 feet above sea level.
Step-by-step explanation:
If you remove weight, a hot balloon goes up. 14+7(feet) = 21 feet above sea level.
They are supplementary angles because their sum equals 180 degrees, and they are adjacent because they share a side.
The walls are vertical so the angle opposite X would be a right angle which is 90 degrees.
X would be 180 - 90 - 35 = 55 degrees
X and 2y - 5 are complementary angles which add together to equal 90:
2y - 5 + 55 = 90
Simplify:
2y +50 = 90
Subtract 50 from both sides:
2y = 40
Divide both sides by 2:
y = 20
Length times width times height
ANSWER
(A)csc angle C equals 3 over 2
EXPLANATION
The cosecant is hypotenuse over opposite.



The secant is the hypotenuse over adjacent.
