Answer:
20 Riyals you receive if you exchange 5 dollars .
Step-by-step explanation:
As given
The money used in Saudi Arabia is the Riyal.
The exchange rate is 4 Riyals to 1 dollar.
i.e
4 Riyals = 1 dollar.
Now calculate for 5 dollars.
5 × 4 Riyals = 5 × 1 dollars
20 Riyals = 5 dollars
Therefore 20 Riyals you receive if you exchange 5 dollars .
We know that angle MKJ is comprised of angle MKL and angle LKJ. That means if we add MKL and LKJ, we should get 80 degrees, which is the measure of angle MKJ.

So, we know that our x is 15. That is not enough to tell whether KL is an angle bisector, because we have to evaluate both MKL and LKJ with x=15, so:

So we see that these two angles are actually bisectors, and the third question best describes this phenomenon.
