A car is traveling up a steep ramp to a parking garage.
The ramp is 445 feet long and rises a vertical distance
of 80 feet. What is the angle of elevation from the car
to the end of the ramp? Round to the nearest degree.

  10°

Step-by-step explanation:

In a right triangle, the ratio of the side opposite an acute angle to the hypotenuse is the sine of the angle. Here, that ratio is 80/445, so we have ...

   sin(angle of elevation) = 80/445

Using the inverse sine function we can find the angle that has this sine value.

  angle of elevation = arcsin(80/445) ≈ 10.36°

The angle of elevation is about 10°.

(d)

step-by-step explanation:

given: the line in the graph passes through points (5,30) and (6,26).

then, the equation of line is:

now, put y=a(n) and x=n,

hence, option d is correct.

b) 1/3 * 1/5

step-by-step explanation:

each smallest part is 1/15 since the written one is 1/5 and it's divided by 3 equal parts. (1/5 )/3 = 1/15 = 1/3 * 1/5
