Answer:
Angle J is 58
Both Angle L and K are 61
Step-by-step explanation:
Since it's an isosceles triangle, it means the base angles are equivalent. In this case, both base angles are 4x + 37
Add all the angles (combine like-terms):
(4x + 37) + (4x + 37) + (5x + 28) = 13x + 102
All the angles of a triangle always sums up to 180 degrees.
13x + 102 = 180
-102 -102
-------------------------
13x = 78
x = 6
Now that you've found x, substitute into the equation for each angle.
