Answer:
the length of the base of the ramp is 28.27 inches
Step-by-step explanation:
The computation of the length of the base of the ramp is shown below:
Let us assume x be the length of the base of the ramp
Now the following formula should be used
tan = opposite ÷ adjacent
tan 23 degrees = 12 ÷ x
x = 12 ÷ tan 23 degrees
= 12 ÷ 0.42447482
=28.27 inches long
Hence, the length of the base of the ramp is 28.27 inches
