Question

The sum of the measures of the angle of a quadrilateral is 360. quadrilateral JKLM has one right angle. Use angle relationships and the measures given below to find the measure of angle K

Answer 1

angle k = 82°

Explanation:

360 - (70 + 118 + 90)

360 - 278 = 82

angle m = 90

angle j = 118 vertical angles are congruent

angle l = 70 Supplemental angles add to 180 (180 - 110)
