Answer:
-12
Step-by-step explanation:
6 ÷ -1/2
Copy dot flip
6 * -2/1
-12
Givens<FOP = 2x + 2
<POQ = 10x - 8
<OF is bisects POQ
Comment
If you multiply POF (which is
2x + 2) by 2 it will be the same size as <POQ because POF is one of the bisected angles of < POQ.
Create an equation and solve
2(2x + 2) = 10x - 8 Remove the brackets.
4x + 4 = 10x - 8 Add 8 to both sides.
4x + 4 + 8 = 10x Combine like terms.
4x + 12 = 10x Subtract 4x from both sides.
12 = 10x - 4x
12 = 6x Divide by 6
x = 12/ 6
x = 2 <<<< answer A
Find <POF< POF = 2x + 2
< POF = 2(2) + 2
<POF = 4 + 2
<POF = 6 <<<< answer B
Find <QOF<QOF = <POF
<QOF = 6 <<<<< Answer C
Find <POQ<POQ = 10x - 8
<POQ = 10(2) - 8
<POQ = 20 - 8
<POQ = 12 <<<<< Answer D
1. X=31
2. X= — 23/3 or -7.8 if putting in decimal form
1. You have that:
-<span>Each blade on a windmill is in the shape of a triangle.
- The triangle has the following dimensions: the base is 7 feet and the height is 4 feet.
- There are four blazer on the windmill.
</span>
2. Then, to solve this problem, you must apply the formula for calculate the area of a triangle, which is:
A=bxh/2
b is the base of the triangle (b=7 feet)
h is the height of the trianlge (h=4 feet)
3. Therefore, you have:
A=bxh/2
A=(7 feet)(4 feet)/2
A=28 feet²/2
A=14 feet²
4. The total area is:
At=Ax4
At=(14 feet²)(4)
At=56 feet²
