1) The sum of one couple vertical angles, two straight lines formed when crossing, is equal 126 degrees. Find a-degree measure of each corner received when crossing these two straight lines. 2) When crossing two straight lines one of the received corners raven1) 75gradus2) the 120th degree. Find-degree measures of other corners.

1) 126:2=63 180-63=117 117*2=234 2) at 1 case there will be 2 corners on the 75th degree and 2 corners on the 105th degree (180-75) in the 2nd case will be 2 corners on 120 degrees and 2 corners on 60 degrees (180-120)
