Since the angles of a triangle add up to 360 degrees, all you need to do is to add the expressions together and equal them to 360. Then solve for x. x on this case equals 57
Answer:
L = 70
Step-by-step explanation:
<j = 55, k < 55
<l = 180 - 110 = 70
L = 70
Y = - 2, when x equals - 8
(n-2)multiple 180 degrees the formula for finding the sum of all angles in a polygon regular here n represents the number of sides of the polygon.
