1) Substitution from definition.
2) We use 
3) We are changing the order of 3 and 
.
4) We add 1 and 3 and we get 
5) Substitution from definition (but the other way than at the beginning).
I think I know the answer but I’m not sure which point it’s asking for :(
Answer:
The answer is 9.5
Step-by-step explanation: I am sure easier way of doing it but I just subtracted 64 from 73.5 and got 9.5 which was correct on edgenuity
Answer: ∠ J = 62° , ∠ K = 59° , ∠ L = 59°
<u>Step-by-step explanation:</u>
It is given that it is an Isosceles Triangle, where L J ≅ K J
It follows that ∠ K ≅ ∠ L
⇒ 5x + 24 = 4x + 31
⇒ x + 24 = 31
⇒ x = 7
Input the x-value into either equation to solve for ∠ K & ∠ L:
∠ K = 5x + 24
= 5(7) + 24
= 35 + 24
= 59
∠ K ≅ ∠ L ⇒ ∠ L = 59
Next, find the value of ∠ J:
∠ J + ∠ K + ∠ L = 180 Triangle Sum Theorem
∠ J + 59 + 59 = 180
∠ J + 118 = 180
∠ J = 62
