We have seen that isosceles triangles have two sides of equal length. The angles opposite these sides have the same measure. Use

dedylja [7]

angle 1 = 180° - 115° (Linear Pair)

angle 1 = 65°

angle 2 = angle 1 = 65° ( Angles on the equal sides of an isosceles triangle )

angle 3 = 180° - (65° + 65°) (Angle Sum Property)

angle 3 = 180° - 130°

angle 3 = 50°

angle 4 = 180° - 65° (Linear Pair)

angle 4 = 115°

angle 5 = 115° (Vertically Opposite Angles)

Two friends, Peyton and Aaron, took summer jobs. The equation y

ICE Princess25 [194]

Answer:

Aaron earns $1.3 per hour more than Peyton

Step-by-step explanation:

Aaron's income is represented by y=29.8x

x represents the number of hours worked

Given that Peyton earns 627 in 22 hours. We want to know how much Aaron earn in 22 hours. We then substitute 22 into the equation as x.

y = 29.8(22)

y = $655.6 in 22 hours

This means that Aaron earns $655.6 in 22 hours.

Therefore, Aaron earns 28.6 dollars more in 22 hours.

We want to know the rate per hour so we divide 28.6 by 22.

rate per hour = 28.6/22

rate per hour = $1.3

Therefore, Aaron earns $1.3 per hour more than Peyton.
