Well sorry but for the first one I can’t read the angles, but I can help for the second one.
The angles inside a triangle add up to 180 degrees, so 68+52=120. Now we need to complete the 180 degrees, so the third angle is 60 degrees. This angle and angle 1 are supplementary angles, so they add up to 180 degrees, meaning that the measure of angle 1 is 60 degrees.
