PKEASE HELP ME FIND ANGLES j, k,l

i’ll mark u brainliest

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.
