Answer:
Height of the ramp is 15.45 ft
Step-by-step explanation:
A ramp for wheelchair accessibility is to be constructed with an angle of elevation of 15 degrees
Height is 6 ft. the ramp forms a right angle triangle
LEt x be the height of the ramp. that is the hypotenuse
sin(theta)= opposite divide by hypotenuse
cross multiply it
x sin(15)=4
divide both sides by sin(15)
x=15.45
Height of the ramp is 15.45 ft
