Answer:
1: 90º
2: 25º
Explanation:
Hey there!
Well we know that all the middle angles are 90º right angles,
so we can conclude that angle 1 is 90º.
All the angles in a triangle add up to 180 so we can set up the following,
65 + 90 + x = 180
Combine like terms
155 + x = 180
-155 to both sides
x = 25º
So angle 2 is 25º.
Hope this helps :)
