Answer:
<K = 55 <L = 55 <M = 70
Step-by-step explanation:
As it is an isosceles triangle, Two sides of the triangle will be equal and their angles will be equal too.
L and K are both = (4x + 3)
All angles in a triangle add up to 180
(4x + 3) + (4x + 3) + (5x + 5) = 180
4x + 3 + 4x + 3 + 5x + 5 = 180
13x + 11 = 180
13x = 180 - 11
13x = 169
x = 169/13
x = 13
<K = 4x + 3 = 4(13) + 3 = 55
<L = 4x + 3 = 4(13) + 3 = 55
<M = 5x + 5 = 5(13) + 5 = 70
