The telescope the cliff and the eagle will from a right tingle as you can see in the picture. The distance between the base of the cliff an the telescope will be the adjacent side of the elevation angle.
The opposite side of the elevation angle will be the height of the cliff 1.3 meters above the ground.
Now, to find the opposite side,
![a](https://tex.z-dn.net/?f=a)
, of our elevation angle, we are going to use the trig function tangent:
![tan(38)= \frac{a}{116}](https://tex.z-dn.net/?f=tan%2838%29%3D%20%5Cfrac%7Ba%7D%7B116%7D%20)
![a=116tan(38)](https://tex.z-dn.net/?f=a%3D116tan%2838%29)
![a=90.6](https://tex.z-dn.net/?f=a%3D90.6)
Finally, we are going to add the height of the telescope and the height of the cliff above the ground:
![90.6+1.3=91.9](https://tex.z-dn.net/?f=90.6%2B1.3%3D91.9)
We can conclude that the eagle is 91.9 meters above the ground; therefore, the correct answer is <span>
B 91.9 m</span>
You add the time she already drove (15+10) and get 25
56-25 = 31 minutes left.
Now if the 56 minute trip includes the stop at the store, we are OK with that answer. If not, then we have to know how long she stopped at the store and add it onto 31 minutes.

Step-by-step explanation:
Answer:
In the equation y = mx + c the value of m is called the slope, (or gradient), of the line. It can be positive, negative or zero. The value of c is called the vertical intercept of the line. It is the value of y when x = 0. When drawing a line, c gives the position where the line cuts the vertical axis.
