15-7 is 8! so 8 is the length of the side with the ?
Answer:
40 degrees
Step-by-step explanation:
Complementary angles have a sum of 90.
y = 90 - x
The angle is 260 degrees less than six times its complement.
y = 6x - 260
90 - x = 6x - 260
350 - x = 6x
350 = 7x
50 = x
This is the measure of the complement.
y = 90 - x
y = 90 - 50
y = 40
This is the measure of the first angle.
200 + 10x = 375
x = 17.5, but round up to 18 because you can’t wash half of a car
If I’m correct I’m pretty sure it is X=5 and Y=-9
