-47 - 15y =-17.....Equation A

-x+ 5y=-13..........Equation B

Solve B for y.

-x + 5y = -13

5y = x - 13

y = (x - 13)/5

Plug y into A.

-47 -15y = -17

-47 -15(x - 13)/5 = -17

-47 -3(x - 13) = -17

-47 -3x + 39 = -17

-3x - 8 = -17

-3x = -17 + 8

-3x = -9

x = -9/-3

x = 3

Now that we know x is 3, plug 3 for x into EITHER Equation A or B (your choice) to find y.

I will let you do that.

Since sides kl and kj are congruent that means that angles klj and kjl are congruent. if angle klj is 58 then that means kjl is also 58. so you take the total number of degrees in a triangle (180) and subtract 58 and 58 (116) which leaves you with 64 ( the degree measure of lkj)
