Question

What is the answer? (Geometry)

Answer 1

`\angle {1} = 90\\\angle {2} = 45\\\angle {3} =55`

Explanation:

1 is 90 because it's placed onto a straight line the equals 180 degrees, therefore it's 90 because the other 2 angles with it are the same, meaning that they had to be 45. 3 is 55 because 90+35=125, and the sum of all 3 angles in a triangle must equal 180, therefore 180-125=55.
