Answer:
Length of the string is
.
Step-by-step explanation:
Diagram of the given scenario shown below,
Given that,
Angle of elevation from the point on the ground to the corner of the canopy is 37°.Distance of the corner of a square canopy to a point on the ground is 15 ft.
To find:- Find the length of the string.
So,
Length of string = AC
Length of Base = AB
angle of elevation = ∠CAB
Here, In Triangle ΔABC,
(∠
) ![= \frac{AB}{AC}](https://tex.z-dn.net/?f=%3D%20%5Cfrac%7BAB%7D%7BAC%7D)
![\cos\ (37) = \frac{15}{AC}](https://tex.z-dn.net/?f=%5Ccos%5C%20%2837%29%20%3D%20%5Cfrac%7B15%7D%7BAC%7D)
![AC= \frac{15}{cos(37)}](https://tex.z-dn.net/?f=AC%3D%20%5Cfrac%7B15%7D%7Bcos%2837%29%7D)
![AC=\frac{15}{0.798635}](https://tex.z-dn.net/?f=AC%3D%5Cfrac%7B15%7D%7B0.798635%7D)
![AC=18.7820 ft](https://tex.z-dn.net/?f=AC%3D18.7820%20ft)
Hence, Length of the string is
.

Answer:
D. 5y^2 - 4y - 1
Step-by-step explanation:
Combine like terms:
(y^2 -y +1) +(4y^2 -3y -2)
= y^2(1 +4) +y(-1-3) +(1 -2)
= 5y^2 -4y -1
