Answer:
c + 1 = 6
Step-by-step explanation:
First, make the equation equal to 6, because Anderson earns $6 per hour.
c + 1 represent how he earns $1 more than half of Carey's hourly rate (c)
So, the equation will be c + 1 = 6
Since this is a right triangle the two acute angles must sum to 90 degrees because a triangle's angles must sum to 180 degrees.
2x+50+3x=90
5x+50=90
5x=40
x=8
So the smallest angle is 3x=3*8=24°
Answer:
x² + y² = 85
Step-by-step explanation:
Using the expansion
(x - y)² = x² + y² - 2xy , then
x² + y² - 2xy = (x - y)² ( add 2xy to both sides )
x² + y² = (x - y)² + 2xy ← substitute given values
= 9² + 2(2)
= 81 + 4
= 85
