Convert all the equations to slope-intercept form:
Lines A, B and C have the same slope as the line 2y-4x=3, so they are parallel and don't intersect it.
Line D has another slope, so it intersects the line 2y-4x=3.
The answer is D.

Both the side are 21 units.
⇒ It is an isosceles triangle.

Property of the angles in a triangle:
----------------------------------------------------
Sum of all angles in a triangle = 180°
----------------------------------------------------
Find x:
----------------------------------------------------
x + x + 38 = 180
----------------------------------------------------
Combine like terms:
----------------------------------------------------
2x + 38 = 180
----------------------------------------------------
Take away 38 from both sides:
----------------------------------------------------
2x = 142
----------------------------------------------------
Divide by 2 on both sides:
----------------------------------------------------
x = 71
----------------------------------------------------
Answer: x = 71°

Answer:
8.53°
Step-by-step explanation:
Observe the attached image.
The ramp forms an alpha angle triangle with an opposite side of 6 ft and an adjacent side of 40 ft.
We know that the tangent of an angle is defined as:
So:
To clear the angle we apply the inverse of the tangent (arctangent) on both sides of the equation:
