Answer:
x = 18 + 9y/2
x-18 = 9y/2
(x-18)x2=9y
2(x-18)=9y
2(x-18) / 9 = y
y= 2(x-18)/9
Step-by-step explanation:
<em>Simplify 9/2y to 9y/2</em>
<em>Then Subtract 18 from both sides</em>
<em>Now Multiply both sides by 2</em>
<em>Then Regroup the terms</em>
<em>now divide both sides by 9</em>
<em>Then you will Switch sides</em>
Answer: x=120°
Step-by-step explanation:
What you are looking for is the value of the exterior angle of the regular polygon.
For a n-sided regular polygon, the external angle is given by the formula 360°/n.
Because the shape in this example is a regular triangle, the value of n is 3.
360°/n
=360°/3
=120°
Therefore, x=120°
.375 because 1/50= .02 and 1/10=.01 which are both less than .375
