Answer: Simplifying
2x + 4 + 2x + 8 + 2x + 8 = 180
Reorder the terms:
4 + 8 + 8 + 2x + 2x + 2x = 180
Combine like terms: 4 + 8 = 12
12 + 8 + 2x + 2x + 2x = 180
Combine like terms: 12 + 8 = 20
20 + 2x + 2x + 2x = 180
Combine like terms: 2x + 2x = 4x
20 + 4x + 2x = 180
Combine like terms: 4x + 2x = 6x
20 + 6x = 180
Solving
20 + 6x = 180
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-20' to each side of the equation.
20 + -20 + 6x = 180 + -20
Combine like terms: 20 + -20 = 0
0 + 6x = 180 + -20
6x = 180 + -20
Combine like terms: 180 + -20 = 160
6x = 160
Divide each side by '6'.
x = 26.66666667
Simplifying
x = 26.66666667

I think you should use the method of tan 30
and then find x by using pythagorean theorem
Answer:
SAS
Step-by-step explanation:
Just do 4*4(four times four)
We assume the best option is the cheapest option, so we need to calculate the total price for each option:
A) $0 + $15×9 = $135
B) $20 + $10×11 = $130
C) $10 + $5×24 = $130
D) $5 + $10×15 = $155
So unless there was a typo in your problem, either of option B or C will be the best option since they are the cheapest at $130.
If you can only select one answer, it becomes a matter of preference. Would you like to pay off the microwave quicker, then choose option B.
If you would like to have more time to pay off the microwave, then choose option C.
Hope this helps!
