Answer:
Step-by-step explanation:
The sum of 12 and a number
(12 + n)
is no greater
< =
then the sum of twice the number and 8
(2n +(-8)) = (2n - 8)

Answer:
<h2>measure of Angle 1 = 81°</h2><h2>Measure of angle 2 = 9°</h2>
Step-by-step explanation:
we need to solve this system
x + y = 90 (1)
x = y + 72 (2)
If we substitute x by y+72 into the equation (1) we will get
(y+72) + y = 90 ⇔ 2y + 72 = 90 ⇔ 2y = 90 - 72 = 18 ⇔ y = 9
then x = 90 - 9 = 81
