We can use SOH CAH TOA to solve this :)
We’re going to use Cosine because the angle and sides given are Adjacent and Hypotenuse- which goes with the CAH part of SOH CAH TOA.
Cos(18) = x/25
Multiply both sides by 25
25cos(18) = X = 23.776
So x = 23.776 cm
I hope this Helps!

Answer:
491,400 ft·lb
Step-by-step explanation:
The mass of the water is ...
M = Vρ = LWHρ = (25 ft)(15 ft)(7 ft)(62.4 lb/ft³) = 163,800 lb
The average depth is 3 ft, so the work required is equivalent to that required to raise this mass 3 ft.
W = (3 ft)(163,800 lb) = 491,400 ft·lb
A cube has 6 sides, and each side has the area of 16 (since 4 times 4 is 16) so if you multiply 16 and 6 you get 96 mm2 as the surface area.
Answer:
x=7
Step-by-step explanation:
x-1
3x-5
______
4x-6
4x-6= 7x-27
-4x -4x
___________
-6= 3x-27
+27 +27
____________
21= 3x
divide both 21 and 3x by 3
= 
7 = x
x=7
