X is a unknown
Number you need to find what the total of all the angles will be and the solve for x
I think it’s B but hopefully i’m right good luck
It would be 12 ones it would be this because you have to add 7+ 5
Answer:
2
Step-by-step explanation:
For Every x value the y value increases by 2
Answer:
21 and 30
Step-by-step explanation:
x + y = 51
x - y = 9
add the two equations and y's will cancel out
2x = 42 divide by 2
x = 21 so put 21 in for x in the top equation and solve
21 + y = 51
y = 30
