Answer:
85 degrees
Step-by-step explanation:
A triangle always has 180 degrees.
This said, since we already know the degrees of 2 angles we can easily find the last one by setting up the following equation.
x+40+55=180
Combine the like terms.
x+95=180
Isolate x by subtracting 95 from both sides.
x=85.
Choice C.
