Answer:
A) 60 miles/hour
Step-by-step explanation:
Answer:
1) Angle AOC + Angle COB = Angle AOB
Angle AOC = X
Angle COB = Y
putting in equation, we get
X + Y = AOB
2) Angle X + Y = AOB (proved above)
AOB = 90° ( given)
Angle X + Angle y = 90°
Angle X is the complement of Y
The equivalent expression is 12x+30y and the area is 156 ft².
Using the distributive property, we have
6(2x+5y)
6*2x+6*5y
12x+30y
If x=3 and y=4,
12*3+30*4
36+120
156
For this case we can model the problem as a rectangle triangle.
We have the angle between the base and the hypotenuse of the triangle.
We have the height of the triangle.
We want to calculate the base of the triangle.
For this, we use the following trigonometric relationship:

Clearing x we have:
Answer:
the shortest horizontal distance that the ramp can span is:
x = 24.02 feet
