Step-by-step explanation:
Answer:
- A. 3x° + (8x - 20)° = 90°
Step-by-step explanation:
The two given angles are complementary and sum to 90°
Therefore correct choice is A.
Answer and explanation
a is $18.00 because Z is a constant
b is y=2.50x+18.00
c is that y=2.50x+z turns into y=$55.50 and then x=15 which we substitute
that leads to 55.50 =2.50(15)+z
and the untimely z = 18.00 dollars .
