Answer:
60
Step-by-step explanation:
180-120= 60
a line is 180 degrees and x is congruent to the angle on the right of 120, meaning if you find the missing angle to that angle(the one next to 120) then you'd get the answer. Knowing the line it 180 and 120 is supplementary to x. x=60.
Subtract 7 from both sides leaving you with
26=-2a
Divide -2 from both sides leaving to you then with
-13=a and this is the answer
It is none of them since -2+5 is 3. Are you sure that's the right equation?
