good. since you know there are two right angles and an angle of 138 already accounted for, the other two angles must sum to equal.... what?

x + x + 22 + 138 + 90 + 90 = (5 - 2) 180 Solve it you get x=100

Mrbonez321...have to solve for KLM. We got 100, we were just unsure.

The sum of the interior angles is (n-2)180 where in n is the number of sides.

100 is the right answer for x

when you are finding <KLM dont you find the angle of the middle letter? So if x=100, You do 100 plus 22 which gives you 122 as your answer. Right?

You sum the 5 angles in term of x and you set the sum equal to 180(5-2) =540 x + x + 22 + 138 + 90 + 90 = (5 - 2) 180 340 + 2 x = 540 2x = 540 -340=200 x=100

Sorry to be a pain, just making sure that solving for KLM is not different than solving for x.

KlM = x + 22= 100 +22 =122
