Answer:
c) 66.73
Step-by-step explanation:
We have been given a right triangle. We are asked to find the value of x for our given triangle.
We can see that x is adjacent side for angle 27 degrees and side Kl is opposite side.
We know that tangent relates opposite side of right triangle to its adjacent side.
Upon substituting our given values, we will get:
Therefore, the value of x is 66.73 for our given triangle and option 'c' is the correct choice.

Formula

Surface area = 2πr² + 2πrh
-------------------------------------------------------------------------
Find Surface Area
-------------------------------------------------------------------------
Total surface area = 2 x π x (13.5)² + 2 x π x (13.5) x (90)
Total surface area = 364.5π + 2430π
Total surface area = 2794.5π
Total surface area = 8774.73 unit² (Take π as 3.14)

John should measure 6 cups of water for his lawn food
The Pythagorean theorem is a^2 +b^2=c^2
In the first example you have to find the length of the hypotenuse( it is opposite of the 90 degrees)
9^2+12^2=c^2
81+144=c^2
225=c^2
(Use a calculator to find the square root of 225)
c=15
