Hello from MrBillDoesMath!
Answer:

Discussion:
34 + 2x = 40 => subtract 34 from both sides
(34-34) + 2x = 40 - 34 => as (34-34) = 0 and 40-34 = 6
2x = 6 => divide both sides by 2
x = 6/2 = 3
Check the answer:
Does 34 + 2x = 40 if x = 3 ?
Does 34 + 2(3) = 40 ?
Does 34 + 6 = 40 ? YES! so the answer checks.
Thank you,
MrB

Answer:
64°
Step-by-step explanation:
KJ = KL, KM is common, and ∠JKM = ∠LKM, so the triangles are congruent.
∴ ∠ J = ∠L = 58°
The three angles of a triangle add up to 180°.
∠J + ∠L + ∠LKJ = 180°
58° + 58° + ∠LKJ = 180°
116° + ∠LKJ = 180°
∠LKJ = 180° - 116°
= 64°
