Answer:
its A
Step-by-step explanation:
The value of x is 30
<u><em>Solution:</em></u>
Given that measure of exterior angle of regular polygon is 2x
The measure of interior angle is 4x
To find: value of x
The sum of an interior angle plus an exterior angle must be equal to 180 degrees (supplementary angles)
measure of exterior angle + measure of interior angle = 180
2x + 4x = 180
6x = 180
x = 30
<em><u>Finding the measure of an exterior angle</u></em>
measure of exterior angle = 2x = 2(30) = 60 degrees
<em><u>Finding the measure of interior angle</u></em>
measure of interior angle = 4x = 4(30) = 120 degrees
Answer:
More expensive
Step-by-step explanation:
FIRST WASHING MACHINE PRICE - $360
SECOND WASHING MACHINE PRICE - MUST NOT BE CHEAPER
$720 x 30% = $216
The additional percentage must make the washing machine more expensive than the first one.
Add and subtract the second term to the expression and factor by grouping.
4k(y-1)(3y+5)
