Answer: SH = 19.23 ft

Step-by-step explanation:

Considering the given triangle SHX, to determine angle SH, we would apply the sine rule. It is expressed as

a/SinA = b/SinB = c/SinC

Where a, b and c are the length of each side of the triangle and angle A, Angle B and angle C are the corresponding angles of the triangle. Likening it to the given triangle, the expression becomes

SH/SinX = XH/SinS = XS/SinH

The sum of the angles in a triangle is 180. Therefore,

X = 180 - (66 + 61) = 53°

Therefore

22/Sin 66 = SH/Sin 53

Cross multiplying, it becomes

SHSin 66 = 22Sin 53

0.9135SH = 22 × 0.7986

0.9135SH = 17.5692

SH = 17.5692/0.9135

SH = 19.23 ft
