Aramp into a building forms an 8° angle with the ground. if the entry point of the ramp is 7 feet from the building, how many feet from the ground is the end of the ramp? round the solution to the nearest hundredth.
0.98 ft
1.22 ft
1.36 ft
2.01 ft

.98 feet

Step-by-step explanation:

This question is asking you for the height of the ramp.  It's a right triangle problem where the length of the base of the triangle is 7 feet and the reference angle is 8 degrees.  We are looking for the side length opposite that of the 8 degree angle.  Since we are looking for the side opposite the angle, and we are given the angle and the side adjacent to it, we need the tangent ratio to solve for the height.  Setting up as the tangent of an angle is equal to the ratio of the side opposite the angle over the side adjacent to the angle:

Multiply both sides by 7 to get

7 tan(8) = x

Do this on your calculator on degree mode and you'll get that the height of the ramp is .98 feet

hello :

70y^8 + 30y^6 = 2 ( 35 y^8 + 15y^6)

the lenght is : 35 y^8

the width is : 15y^6
