A15 ft ladder leans against the side of a house. the top of the ladder is 13 ft off the ground. find x, the angle of elevation of the ladder. round your answer to the nearest tenth of a degree.

x= 60.1 degrees

Step-by-step explanation:

The triangle forms a right angle triangle

Opposite side of angle x = 13 ft

Hypotenuse of the triangle = 15

We know the opposite side and the hypotenuse

So we use trigonometric formula sin(x)

When we move 'sin' to the other side it becomes 'sin^-1'

x = 60.073565

b. 1.25 hr

step-by-step explanation:

if you have a constant speed of 60 mph, then you have a ratio between 60 mi. to 1 hr. dividing both sides by 60 we get the ratio

1 mi. to

then mult. both sides by 75 we get the ratio

75 mi. to

simplifying we get

75 mi. to

or 1.25 hr.
