Answer:
The ratio representing the tangent of ∠K is 40 : 9.
Step-by-step explanation:
Consider the right-angles triangle KLM below.
The angle M is 90°.
KM = perpendicular (<em>p</em>) = 40
ML = base (<em>b</em>) = 9
LK = hypotenuse (<em>h</em>) = 41
The tangent of an angle is the ratio of the perpendicular length to the length of the base.
Compute the tangent of ∠K as follows:

Thus, the ratio representing the tangent of ∠K is 40 : 9.
The bottom is (25 x 20) = 500 of whatever those units are, squared. Each long side is (25 x the depth of the pool, which we don't know), and each end is (20 x depth).
Simply state that it is a parallelogram according to the parallelogram theorm. If you need the segments here's an example (A ≈ B and C ≈ D) thats it!
Answer:
x = 19
Step-by-step explanation:
In an isosceles trapezoid the base angles are congruent, thus
5x - 20 = 2x + 37 ( subtract 2x from both sides )
3x - 20 = 37 ( add 20 to both sides )
3x = 57 ( divide both sides by 3 )
x = 19
