A skateboard ramp is built on an incline it rests on a porch that is 1.3m high. The bottom of the ramp is placed 2.5m from the porch. What is the angle that the ramp forms with the ground?

The angle that the ramp forms with the ground is 27.5°

Step-by-step explanation:

Check the attachment for the figure.

Using the SOH CAH TOA trigonometry identity

For TOA

Tan(theta) = opposite/adjacent

Given opposite = 1.3m(side facing the angle of inclination

Adjacent = bottom of the ramp= 2.5m

Tan(theta) = 1.3/2.5

Tan(theta) = 0.52

theta = arctan0.52

theta = 27.5°

stop cheating

step-by-step explanation:

the answer would be 1 1/72

step-by-step explanation:

you can rewrite the equation by separating the parts and then solving individually:

10-9=1

1/8 - 1/9=

find l c d and then combine:

1 1/72
