At a local restaurant, a couple ordered two dinners for $12.50 each and two drinks for $1.50 each. If the couple left an 18% tip
aivan3 [116]
First, you have to add up the cost of each meal and drink:
12.50 + 12.50 + 1.50 + 1.50 = 28


$28 is the cost before the tip. Now multiple 28 by .18 to find the tip:
28 x .18 = 5.04

The tip was $5.04. Add the 28 and the 5.04 to get the total cost:
28 + 5.04 = 33.04

ANSWER:
The total cost was $33.04

In the figure, three line segments cross at a common point. Angle A is 45°, and angle E is 85°. What is the measurement of angle
katen-ka-za [31]

Answer: Measure angle H = 42°


Step-by-step explanation:

"In a triangle, the measure of the exterior angle is equal to the sum of the measures of the two non-adjacent angles to the exterior angle"

In given we have,

angle E is an exterior angle to triangle DFH

The two non-adjacent angles to angle E are angles D and H

Based on the above rule,

measure angle E = measure angle D + measure angle H

We are given this:

angle E = 87°

angle D = 45°

Substitute with the givens in the above rule and solve for the measure of angle H as follows:

angle E = angle D + angle H

87° = 45° + measure angle H

measure angle H = 87° - 45°

measure angle H = 42°

Hope this helped!
