Rápido y fácil, trigonometría. Urgente porfavor

Answer:

The angle $\theta$ measures approximately $28.81^o$

Step-by-step explanation:

Since this problem involves the finding of an angle in a right angle triangle for which we know the opposite side and the adjacent side, the trigonometric function that relates them is the tangent:

$tan(\theta)=\frac{opposite}{adjacent}$

Then, for our case we get a starting equation that reads:

$tan(\theta)=\frac{opposite}{adjacent} \\tan(\theta)=\frac{7.7}{14}$

and for which we need to solve for $\theta$ . Then we use the arctangent function to get the final answer:

$tan(\theta)=\frac{7.7}{14} \\\theta=arctan(\frac{7.7}{14})\\\theta= 28.81^o$

Ricky has a 26-foot ladder. He must have the bottom of the ladder 10 feet from the wall. Will he be able to reach a roof that is

matrenka [14]

Check the picture below.

the ladder is 26ft, the roof is 24ft above, so the ladderis 2ft longer than needed, if you move the ladder 10 feet away, will it give 24 or more? well, you know already.
