Answer:
A. 8.66 feet
B. 12.59 feet
C. Area of triangle when 
is 129.9 square feet. Area of triangle when 
is 188.85 square feet. Increasing the angle 
increases the area.
Step-by-step explanation:
The equation that models the height of the triangle is:
Where,
is the height, and
- is the angle
A.
When , the height is:
B. When ![\theta=40[/tex\ , the height is:[tex]y=15Tan40\\y=12.59](https://tex.z-dn.net/?f=%5Ctheta%3D40%5B%2Ftex%5C%20%2C%20the%20%3Cstrong%3Eheight%3C%2Fstrong%3E%20is%3A%3C%2Fp%3E%3Cp%3E%5Btex%5Dy%3D15Tan40%5C%5Cy%3D12.59)
C. <em>To find the area of the isosceles triangular shaped garden, we use the </em><em>formula for the area of the triangle</em><em>:</em>
Where,
- A is the area
- b is the base, which is given as 30 feet, and
- h is the height [8.66 feet when the angle is 30 & 12.59 when angle is 40]
<u>When Vance uses , the area is</u>:
square feet
<u>When Vance uses , the area is</u>:
square feet
So we see that when the angle is more, the area is also more.
To find the angle use arc tan (-5/-7) which simplifies tips arctan(5/7). arc tan is tan to the power -1, which is also called inverse tan. The heading of the angle, if you drew this out on a graph your angle would be in the third quadrant and therefore the heading is south of west.
