a quadrilateral has two angles that measure when it's 150° and 80°. The other two angles are in the ratio of 6:7. what are the measures of those two angles?

Answer 1

60 and 70. The sum of the 4 angle of a quadrilateral is 360, and the first two angle sum to 230, so the remaining two angle must sum to 130. Because the angles are in a ratio of 6:7, their angles can be written as 6x and 7x, so we have 6x + 7x = 130 since those angles sum to 130. This gives us x = 10, so the angles are 60 and 70.

Answer 2

150+80+6x+7x=360.............................
