It just means that the angles i and r are congruent
ROQ is 124
so 124 is split in half by line OP
124/2=62
angle r=angle i=62 degrees
now
ROK
we see that the other side is a right angle
so POK must be a right angle as well

POR+ROK=POK=90
angle r=62=POR
so
62+ROK=90
minus 62 both sides
ROK=28 degrees

you forgot to account for angle LOQ in your equation
or maybe you should do 56/2 since it is a bisector

anwya, ROK=28 degres

Since roq = 124 and that they are equal, qol and rok are also equal,
so just take (180-124)/2= 28

After 4,000 gallons of water were added to a large water tank that was already filled to 3/4 of its capacity, the tank was then

Answer: The correct option is

(E) 80,000.

Step-by-step explanation: Given that after adding 4,000 gallons of water to a large tank that was already filled to $\dfrac{3}{4}$ of its capacity, the tank was then at $\drac{4}{5}$ of its capacity.

We are to find the number of gallons of water that the tank hold when filled to capacity.

Let the tank can hold x gallons of water when filled to capacity.

Then, according to the given information, we have

$\dfrac{3}{4}x+4000=\dfrac{4}{5}x\\\\\\\Rightarrow \dfrac{4}{5}x-\dfrac{3}{4}x=4000\\\\\\\Rightarrow \dfrac{16-15}{20}x=4000\\\\\Rightarrow x=4000\times20\\\\\Rightarrow x=80000.$
