Noah wants to clean his second story windows and plans to buy a ladder that will reach at least

Lina20 [59]

Answer:

Noah should buy a ladder of length greater than 28.1 ft to reach at least 22 feet height.

Step-by-step explanation:

Given:

Noah has to reach at least 22 ft height.

Angle made by the base of ladder with the ground = 51.5°

To find the length of the ladder.

Solution:

On drawing the situation, we get a right triangle. The hypotenuse of the triangle represents the length of the ladder.

In triangle ABC.

∠C = 51.5°

AB = 22 ft

Applying trigonometric ratio to find AC (length of the ladder).

$\sin\theta = \frac{Opposite\ side}{Hypotenuse}$

$\sin C=\frac{AB}{AC}$

Plugging in values.

$\sin 51.5\°=\frac{22}{AC}$

Multiplying AC both sides.

$AC\sin 51.5\°=\frac{22}{AC}\times AC$

$AC\sin 51.5\°=22$

Dividing both sides by $\sin 51.5\°$

$\frac{AC\sin 51.5\°}{\sin 51.5\°}=\frac{22}{\sin 51.5\°}$

$AC=\frac{22}{\sin 51.5\°}$

$AC=28.1\ ft$

Thus, Noah should buy a ladder of length greater than 28.1 ft to reach at least 22 feet height.

5.3.21 Solve the equation P= r+t+s for r (Simplify your answer.)

Sever21 [200]

Answer:

r = P -t -s

Step-by-step explanation:

This is a one-step linear equation in r. Subtract the terms that don't contain r:

P = r + t + s . . . . . . . . . . given

The terms on the right that don't include r are (t+s). We want to subtract that to get r by itself.

P -(t+s) = r +(t+s) -(t+s) . . . subtract (t+s)

P -t -s = r . . . . . . . . . . . . . . simplify

r = P - t - s
