eimsori [14]

Answer:−9a+10b−23

Step-by-step explanation:−9a+3b−a+7b−13+a−10

Combine −9a and −a to get −10a.

−10a+3b+7b−13+a−10

Combine 3b and 7b to get 10b.

−10a+10b−13+a−10

Combine −10a and a to get −9a.

−9a+10b−13−10

Subtract 10 from −13 to get −23.

−9a+10b−23

kakasveta [241]

Coplanar lines are line witch lie on the same lie on the same plane. two parallel lines or two intersecting lines always lie in a plane. Thus, two line are coplanar, if and only if they are either parallel or intersecting. lines in three dimensional space are coplanar, only if they are not skewed lines.

A video camera is being mounted on a bank wall so as to have a good view of the head teller. Find the angle of depression that t

Sever21 [200]

Answer:

The angle of depression of the lens must be 26.3°

Step-by-step explanation:

Here we have a right triangle with the opposite side to the angle equal to 5.93 feet and the adjacent side to the angle equal to 12.02 feet. Therefore we just need to use the tangent definition to find the angle.

$tan(\alpha)=\frac{5.93 ft}{12.02 ft}=0.49$

$\alpha=tan^{-1}(0.49)=26.3^{\circ}$

The angle of depression of the lens must be 26.3°

I hope it helps you!
