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.

Answer: Approximately 0.677</h3>
Explanation:
Add up the values in the plan A column. There are 10+12+16 = 38 people who prefer plan A.
Add up the values in the "40-49" row to find that 16+8 = 24 people are ages 40 to 49.
We have 38+24-16 = 46 people who either prefer plan A, are aged 40-49, or fit both descriptions. I subtracted off 16 because those 16 people were counted twice when adding 38 and 24.
An alternative way to get this value of 46 is to add up everything that is in column1 or row 3 (or both). So that would get 10+12+16+8 = 46.
Now add up everything in the table to find out how many people were surveyed total. That would be 10+7+12+15+16+8 = 68 people overall.
The probability of someone liking plan A, or being age 40-49, or both is 46/68 = 0.6765 approximately. Rounding to 3 decimal places gives 0.677
