Find the measure of an angle that is 30° less than its supplement.

Step-by-step explanation:

x+(x-30)=180

2x=180-30  

2x=150

x=150/2

x=75 degrees ans. for the smaller angle.

180-75=105 degrees for the larger angle.

step-by-step explanation:

two pairs of adjacent sides are of equal length. this implies that one diagonal divides the kite into congruent triangles, and so the angles between the two pairs of equal sides are equal in measure. it also implies that the diagonals are perpendicular.
