In the following diagram \overline{DE} \parallel \overline{FG}
zloy xaker [14]

Answer:

<x= 31°

Step-by-step explanation:

m<BCA= m<GCJ (vertical angles)

m<BCA= 59° (substitution)

Since line KL is perpendicular to line FG, the angle formed at point B is 90°.

Therefore, m<ABC=90°

m<BAC+m<ABC+m<BCA=180° (sum of triangle)

m<BAC+90°+59°=180° (substitution)

m<BAC+149°=180°

m<BAC=180°-149°

m<BAC=31°

<x=<BAC (vertical angles)

m<x=31° (substitution)

Gwar [14]

Answer:

skew

Step-by-step explanation:

Perpendicular lines must intersect. In fact, they intersect forming right angles.

Lines AC and RC are not in the same plane and do not intersect.

They are called "skew lines."

The height is??? I somehow got the width
EleoNora [17]

To find the maximum height, we must find the x value at which the maximum height occurs.

The maximum height occurs at x = 0 because that is where y is the largest.

When we plug x= 0 into the function that is given in the question, we get 630 ft.

Hope it helps!
