1) Here, as the two angles are same, it would be isosceles triangle with two equal sides, so x = 5
y = x√2
y = 5√2 or 7.05
In short, Your Answers would be: x = 5 & y = 7.05
2) We know, Sin Ф = P / H
Sin 30 = 27 / H
1/2 = 27 / H
H = 27 * 2
H = 54
In short, Your Answer would be 54 Feet
Hope this helps!
