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.
Answer:
3.3 x 10⁻⁴
Step-by-step explanation:
Given expression:
To solve this problem;
10° = 1
So;
= 
x 10⁻³
= 0.33 x 10⁻³
= 3.3 x 10⁻¹ x 10⁻³
= 3.3 x 10⁻⁴
Answer:
31
Step-by-step explanation:
Increases by 7 each time
The red figure is smaller so it is a reduction.
To find the scale factor divide the length of the smaller shape by the length of the larger shape:
9/15 this can be reduced to 3/5
