If you place a 89-foot ladder against the top of a 80-foot building, how many feet will

Nuetrik [128]

Answer:

$\large \boxed{\text{39 ft}}$

Step-by-step explanation:

Let x be the distance from the foot of the ladder to the base of the building.

We have a right triangle, so we can use Pythagoras' Theorem.

$\begin{array}{rcl}80^{2} + x^{2}& = & 89^{2} \\6400+ x^{2} & = & 7921\\x^{2} & = & 1521\\x & = & \sqrt{1521}\\& = &\mathbf{39}\\\end{array}\\\text{The foot of the ladder will be $\large \boxed{\textbf{39 ft}}$ from the base of the building,}$

Find each angle measure.<br>

Vitek1552 [10]

Answer for 11-13: m<2: 150, m<6: 150, m<7: 150

Step-by-step explanation:

There is 180 degrees in a straight line. If one part of the line (angle) is 30 degrees, then the other part is 150. If you look at the image, you would see that m<2 is congruent to m<6 ,which means same, and m<7 is congruent to m<3.

Answer for 14-16: m<EBG: 150, m<AGH: 150, m<DHF: 30.

Step-by-step explanation:

4x = 150 2x + 50 = 150

x = 37.5 2x = 150 - 50

4(37.5) = 150 2x = 100

x = 50

2(50) + 50 =

100 + 50 = 150
