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.

9/10 or 0.9

Step-by-step explanation: hope this helps
