108 is the answer to your question
Complementary angles ⇒ the angles add up to 90°
∠A and ∠B are complementary ⇒ ∠A + ∠B = 90°
∠A + ∠B = 90°
Plug in the values for ∠A and ∠B:
(3x - 8) + (5x + 10) = 90
Open the brackets:
3x - 8 + 5x + 10 = 90
Combine like terms:
8x + 2 = 90
Subtract 2 from both sides:
8x = 88
Divide both sides by 8:
x = 11
Answer: x = 11

Answer:</h2><h2>
They should travel 120 mils in one day for both rental agencies to cost the same amount to rent</h2>
Step-by-step explanation:
A rental car agency charges $30.00 per day plus per mile $0.15.
Let x be the number of miles travelled by car
Their total cost = 30 + (0.15x) ... (1)
Another rental car agency charges $36.00 per day plus $0.10 per mile
Their total cost = 36 + (0.10x) ... (2)
Equating (1) and (2), we get
30 + (0.15x) = 36 + (0.10x)
36 - 30 = 0.15x - 0.10x
6 = 0.05x
x = 120 miles
They should travel 120 mils in one day for both rental agencies to cost the same amount to rent
