Answer:

B. 40

Step-by-step explanation:

We know that the large angle is 90 degrees as it is a right angle. Thus, 10+2x=90 (I don't know how to include degree symbols). We solve: 2x=80, so then x=40. Thus, x is forty degrees and the answer is B.

Answer:

40

Step-by-step explanation:

There is a bisector splitting a 90-degree angle into 2 parts, we are given that one of them is 10. This can only mean the other side is 80 degrees in total.

and 80/2 is 40
