Question

In quadrilateral JKLM, angle J is equal to 110⁰, angle K is (x+10)⁰, angle L is x⁰, and angle M is 90⁰.
Write an equation and solve for x. Find the measurement of angle K. Show each step of your work. In your response, be sure to type the word “angle” and not the symbol “<,” for example, “angle ABC” not “ 11 years ago

Answer 1

simple sum of alll the angles of a quadrilateral is always 360;
so,
angle MJK + angle JKL + angle KLM + angle LMJ = 360;
110 + (x+10) + x + 90 =360;
2x=150;
x=75 ans
