Answer:
151 degrees
Step-by-step explanation:
This triangle has supplementary angles, so we need the triangle to add up to 180 degrees.
Start off with 61 degrees, below the 61 degrees symbol, there is a right angle under it, a right angle equals to 90 degrees. Then subtract 90 from 61, so the last angle is 29 degrees.
Then subtract 180 from 29, then your answer is 151 degrees.
