The statement gives you the function that models the Area as a function of angle theta, and is telling the value of this angle.
Then, you only need to replace the value of the angle in the function, to obtain the requested area.
<span>A(Θ) = 16 sin Θ • (cos Θ + 1).
Θ = 60°
A(</span>60°<span>) = 16 sin(</span><span>60°) * [cos(</span><span>60°) + 1 ] = 16 * (√3) / 2 * [1/2 + 1] = 8(√3) * 3/2 = 12√3 ≈ 20.79

Answer:
29
Step-by-step explanation:
Given
- 5x + 4 ← substitute x = - 5 into the expression
= - 5(- 5) + 4 = 25 + 4 = 29
Answer:
60
Step-by-step explanation:
2x+5+x-5=180
add the common things
3x=180
divide stuff
x=60
Answer: 
Step-by-step explanation:
Given
Angelo drew a model with his drawing length 10 inches tall
The actual pole length is 15 feet tall
drawing scale is the ratio of drawing length to the actual length i.e.
Answer:
1 - s = s - 4 (s=2.5)
Step-by-step explanation:
If you write the equation down, you get 3-(s-1) = 3(s-4), which (when you divide each side by 3), gives you -s+1=s-4. If you add s to both sides, you get 1 = 2s - 4, and after adding 4, you get 2s = 5, and s = 2.5
