why is angle 1, 60 degress

Angle 1 is 60 degrees because angles A, B, and C form a triangle, and the sum of the angles in a triangle is always 180 degrees. Since angle A is 90 degrees (it's a right angle) and angle B is 30 degrees, angle C must be 60 degrees to make the sum of the angles in the triangle 180 degrees.
