Yas! systems of equations convert one equation so that a single variable is one one side x = 65 - 2y plug it in the other equation 2(65 - 2y) + 3y = 105 130 - 4y + 3y = 105 130 - y = 105 25 = y
The measure of angle 1 is 75 degrees because it is a corresponding angle with the one given of 75 degrees the measure of angle 2 is 105 degrees because it forms a supplementary angle with the one next to it that is 75 degrees. (this means they add up to 180 degrees.
