Find all the angles formed at the intersection of two parallel straight lines a and b secant to c, if: a) one of the angles is 150 °; b) one of the angles is 70 ° larger than the other.
a) Four angles will be 150 degrees each and 4 by 30. Tk two angles are adjacent, one is 30, and the other is 150, they have vertical angles and corresponding, and they are equal to the original.
b) the sum of the snow angles is 180
(180-70) / 2 = 55 degrees
4 angles of 55 degrees and 4 angles of 125 degrees
