<h3>
Answer: 13x-8 units by 13x+8 units</h3>
Explanation:
Factor using the difference of squares rule

The rectangular pool has dimensions of 13x-8 units by 13x+8 units.
The right triangles are all similar, so the hypotenuse is proportional to the short side in each case.
m/5 = (14 +5)/m
m^2 = 5*19 = 95
The best choice is ...
C. √95
Sin²β +cos²β=1
cos²β=1-sin²β
cos²β=1-(4/7)²
cos²β=1-16/49=49/49-16/49=33/49
cosβ=√33/√49=√33/7
