Can someone explain to me how to do

A straight line is 180°, so you can do this:

118 + y = 180

y = 62°

The triangle is an isosceles triangle, so the other angle of the triangle is 62° too.

Now that you have 2 of the 3 angles, you can go find the 3rd angle.

62 + 62 + z = 180

z = 56°

Now you can go find ∠2

56 + ∠2 = 180

∠2 = 124°

124 = 12x + 4

120 = 12x

10 = x

answer: the answer is 30 miles per hour.

ft/s -> mphmph = ft/s 1.466667mph = 44 divided by 1.466667mph = 30.00000
