Answer:
Step-by-step explanation:
To find the angles of any shape with all sides equal in length, we use the formula:
, where n is the number of sides
For a pentagon, we get the equation:
Thus the measure of each in a pentagon if the lengths of all five sides are equal is 108 degrees.
Hope that helps!
-15 and -2 don’t make +17

Let the number of students in the class be x
Let the number of pieces of gum she gave out be 3x
Equation
3x + 8 = 168 This will not work out evenly. Let's try x - 1. The reason for that is because she may not give out anything to herself.
3(x - 1) + 8 = 168 This doesn't work either.
Well we have to choose. It's a rounding problem.
3x + 8 = 168 Subtract 8 from both sides.
3x = 168 - 8 Combine
3x = 160 Divide by 3 on both sides.
x = 160 / 3
x = 53.333333333
Since that can't be, we could say there were 53 students.
3x
slope intercept form is y = mx + b
so the answer is y = 2x - 3
