Answer:
Find below the calculations of the two areas, each with two methods. The results are:


Explanation:
<u>A) Method 1</u>
When you are not given the height, but you are given two sides and the included angle between the two sides, you can use this formula:

Where,
is the measure of the included angle.
1. <u>Upper triangle:</u>

2. <u>Lower triangle:</u>

<u></u>
<u>B) Method 2</u>
You can find the height of the triangle using trigonometric properties, and then use the very well known formula:

Use it for both triangles.
3. <u>Upper triangle:</u>
The trigonometric ratio that you can use is:

Notice the height is the opposite leg to the angle of 60º, and the side that measures 100 units is the hypotenuse of that right triangle. Then:


3. <u>Lower triangle:</u>

Answer:
(2, -39)
Step-by-step explanation:
f(x)=-3(x+2)^2+9
f(2)=-3(2+2)^2+9
f(2)=-3(4)^2+9
f(2)=-3(4)(4)+9
f(2)=-3(16)+9
f(2)=-48+9
f(2)=-39
Answer:
v = 10
Step-by-step explanation:
2 = v - 8
add 8 to both sides
10 = v
