Question

PKEASE HELP ME FIND ANGLES j,k,l i’ll mark u brainliest

Answer 1

Answer:

Both angles have a measure of 73 degrees

Step-by-step explanation:

5x+28=4x+37

x+28=37

x=9

(5(9)+28)                     (4(9)+37)

(45+28)                       (36+37)

(73)                               (73)

Answer 2

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.
