Step-by-step explanation:
7 x 8 x 11 x 2 = 11 x 7 x 2 x 8
1232 = 1232
Hope it helps!
a = 40° (vertical angles are equal)
b = 90 - 40 = 50° (sum of all interior angles in a triangle is equal 180 but one angle is 90° so a + b = 90°)
c = 180 - 65 = 115° (angle c and 65° are supplementary angles, so sum = 180°)

Answer:
$23.6
Step-by-step explanation:
The lunch normally costs $20
But you give a 18% TIP on top of that
Certainly, it will cost more. Lets find out how much exactly.
First, we need to find 18% of 20 and then ADD it to 20 to find FINAL LUNCH COST.
To convert percentage to decimal, we divide by hundred. After that we multiply with 20 to get 18% of 20. Process shown belowL
18% = 18/100 = 0.18
Then,
0.18 * 20 = $3.6
Adding to $20, we get total cost:
20 + 3.6 = 23.6 dollars
Total Cost = $23.6
