Answer:
32.7 degress
Step-by-step explanation:
In this question we are to find the value of the angle
The best way to do with the information given is the cosine rule
Mathematically that would be;
y^2 = x^2 + z^2 -2xzCosY
where x = 90 ft , y = 55ft and z = 50 ft
Plugging the values we have;
55^2 = 90^2 + 50^2-2(90)(50)CosY
-7575 = -9000cosY
cosY = 7575/9000
cosY = 0.841666666667
Y = cos^-1 0.841666666667
Y = 32.68 degrees which is 32.7 to the nearest tenth
