Answer:

Angle 1 and angle 3 are congruent by Vertical Angle theorem. It can also be proven using reflection.

Step-by-step explanation:

Two line segments which intersect form one intersection point which has 4 angles from it. Angles 1 and 3 will be directly across from each other off this intersection point. Vertical Angle Theorem states these are congruent.

Angles can be reflected across this intersection point. Since reflection preserves size and shape, these two angles will land on one another and be the same angle.

The sales tax on a $350 computer is $ 22.75. find the sales tax rate.
likoan [24]

Set up an equation to solve for the tax rate, x:

350(x) = 22.75\\x = \frac{22.75}{350}\\x = 0.065\\x = 6.5%


We can conclude that the tax rate on the computer was 6.5 percent.
