Final answer:
The size of angle x, when adding angles of 65 degrees and 35 degrees together, is 100 degrees, which corresponds with option A.
Step-by-step explanation:
The question is asking to find the size of angle x given that it is 65 degrees and 35 degrees. Since angle sizes are absolute measurements, you cannot have an angle be two different measurements at the same time. The question might be misinterpreted or missing additional context. For instance, if we are looking for the sum of two angles, one of which is 65 degrees and the other is 35 degrees, then the size of angle x would be the total when these two angles are added together.
To calculate:
- Add the two given angles: 65 degrees + 35 degrees = 100 degrees.
Therefore, the size of angle x is 100 degrees, which matches option A.
