10.) The measure of angle 1 is 131° according to the Alternate Interior Angles Theorem. The measure of angle 2 is 49° because 180° - 131° = 49°. I can do this because of the Linear Pair Postulate.
11.) The measure of angle 1 is 65° according to the Vertical Angles Theorem. The measure of angle 2 is 65° according to the Corresponding Angles Theorem.
Hope this helps!
