Answer: 37º
Step-by-step explanation:
If the measure of the angle ABC must be equal to 180º, make an equation adding all the other values and solve for y.
yº+29º+40º+2yº=180º
Combine like terms;
3yº+69º=180º
Subtract 69º
3yº=180º-69º
3yº=111º
Divide by 3º
yº=111º/3º
yº=37º
Answer:
I think the correct answer is 37
You add all the angle measures up together to equal 180 then you combine like terms to get 3y + 69 =180
So you do 180 - 69 then divide that number by 3 to get y
