to get from 10 to 0 is 10 units and from 0 to -15 is 15
10+15 = 25
Answer:
50 degrees
Step-by-step explanation:
x + y = 90
x = 2y - 30
2y - 30 + y = 90
3y - 30 = 90
3y = 90 + 30
3y = 120
y = 120/3
y = 40
x = 2y - 30
x = 2(40) - 30
x = 80 - 30
x = 50 <====== angle x
The -3 and 2 are just the numbers you multiply by to get the variable 's' have opposite values in the 2 equations so that when you add the 2 equations, they would cancel out
