Answer:

35° , 55°

Step-by-step explanation:

Let one angle be x.

It's complementary angle is = (90 - x)°

According to the question ,

x - (90 - x) = 20

=> x - 90 + x = 20

=> 2x = 90 - 20 = 70

=> x = \frac{70}{2} = 35

Solve the system of equations by substitution
r-ruslan [8.4K]
We have y=2x and y=x+2
They both equal y, so substitute the first equation for y in the second equation.
2x=x+2
Let’s get x to one side. Let’s subtract x from both sides.
X=2
Since x=2, just plug in 2 for x.
2+2=4
So,
X=2
Y=4

Total Cost = $44 + 2($23)

2 × 23 = 46

Total Cost = $44 + $46 = $90

The total cost is $90, choice B.
