We know that

<span>If the slope of the angle from the vertex is positive, then it is an angle of elevation.</span>

<span>If the slope of the angle from the vertex is negative, then it is an angle of depression.</span>

The angle of elevation is congruent to the angle of depression because they are alternate interior angles

in the picture

∠ 1 is the angle of elevation from submarine to the boat

∠2 is the angle of depression from boat to submarine

∠3 is the angle of elevation from boat to the lighthouse

∠4.is the angle of depression from the lighthouse to the boat


therefore

the answer is

∠2 is the angle of depression from boat to submarine

Kiran has LaTeX: 10\frac{1}{2} 10 1 2 feet of lumber and wants to make a bookshelf. Kiran needs two side panels that are each La
Musya8 [376]

Answer:

A) LaTeX: \frac{5}{6} 5 6 feet

Step-by-step explanation:

Kiran has 10 1/2 feet of lumber and wants to make a bookshelf.

Kiran needs two side panels that are each 5 2/3 feet.

1 side panel = 5 2/3 feet

2 side panels =

2 × 5 2/3

2 × 17/3

= 34/3

= 11 1/3 feet

Kiran would need 11 1/3 feet of lumber.

Kiran already has 10 1/2 feet

How much more lumber does Kiran need in order to make the side panels?

This is calculated as:

11 1/3 - 10 1/2

11 - 10 + (1/3 - 1/2)

1 + ( 2 - 3/6)

1 + (-1/6)

1 - 1/6

= 5/6

Hence, Kiran need 5/6 feet more of Lumber.
