The answer I got was 12 if needed I can take a picture of how I worked it
Answer:
a and b
Step-by-step explanation:
15x-60=120
15x-60-60=120-60
15x=60
15x/15=60/15
x=4
3x=12
3x/3=12/3
x=4
Answer:
x = 9
Step-by-step explanation:
Sum of all angles of a triangle = 180
63 + 7x + 6x = 180
63 + 13x =180
13x = 180 - 63
13x = 117
x = 117/13
x = 9
So what’s the question? What are we trying to find?
