Answer:
m∠4 = 23°
Step-by-step explanation:
1- getting the value of x:
We know that KM bisects ∠NKL, this means that:
∠3 = ∠4 = x
Now, we know that ∠NKJ, ∠3 and ∠4 form a straight angle.
This means that their summation is 180°
We can now get the value of x as follows:
180 = ∠NKJ + ∠3 + ∠4
180 = 5x + 19 + x + x
180 = 7x + 19
180 - 19 = 7x
161 = 7x
x = 23
2- getting ∠4:
From part 1, we got that x = 23
We are given that:
∠4 = x
This means that:
∠4 = 23°
Hope this helps :)
