Please help me answer this question

x = 7, y = 16

Step-by-step explanation:

the sides with measure 2x + 5 and x + 12 are congruent, so

2x + 5 = x + 12 ( subtract x from both sides )

x + 5 = 12 ( subtract 5 from both sides )

x = 7

Then

x + 5 = 7 + 5 = 12

The sides with measure y - 4 and x + 5 are congruent, so

y - 4 = x + 5, that is

y - 4 = 12 ( add 4 to both sides )

y = 16

we know that

applying the law of sines

°

so

∠j=18°

∠k=29°

∠l=180-(18+29)=133°

the answer part a) is

the measure of angle k is  ≈29°

part b)  the measure of angle k could also be

(180-29)=151°

so

∠j=18°

∠k=151°

∠l=180-(18+151)=11°

the answer part b) is

the measure of angle k could also be 151°
