Answer:
C=180 degrees
Step-by-step explanation:
A+B+C=180
A is vertical with 70. A=70 Degrees
Bis supplementary with 135. So 135+B+180, 180-135=45, B=45 degrees.
To find C you need to use the triangle sum theorem. So that means if you add up all 3 sides you could get 180 degrees,
45+70=95
180-95=85
70(A)+45(B)+85(C)=180
