Answer:

Height of slide = 5 feet (Approx.)

Step-by-step explanation:

Given:

Length of slide = 12 feet

Angle of depression = 25°

Find:

Height of slide

Computation:

Length of slide = Hypotenuse

Height of slide = Perpendicular

Using trigonometry function;

Sin θ = Perpendicular / Hypotenuse

Sin 25 = Height of slide / 12

0.422 = Height of slide / 12

Height of slide = 12 x 0.422

Height of slide = 5.064

Height of slide = 5 feet (Approx.)

Leviafan [203]

$A=\frac{1}{2}(b_1+b_2)h=13687.5\\\frac{1}{2}((150)+(215))h=13687.5\\(365)h=27375\\h=75$

h = 75 yards.

Floor tile costs $11 $11 per square yard. How much will it cost to tile a bathroom that is 90 90 square feet?

ira [324]

Answer: $1980

Step-by-step explanation:

Well, based off of the question being asked, I assume that you will need to pay $11 for 90 square footage of tiling, and then the same for the other square footage of tiling. Therefore your answer will be $1980. If you are looking for the equation, it is (11x90)=990 (990)2 = 1980

you do not need to multiply 11 by 90 again because you already know the answer.
