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

When the whole is the same, why does it take 4 copies of 1 tenth to equal 2 copies of 1 fifth?

vaieri [72.5K]

Because you can split the same whole into different parts. You can split a cake into 10 peices and eat 4 peices of the cake. That would be eating 4/10 of a cake. That would equal eating the same amount of cake if you split the cake into 5 peices and ate 2 of them.

Jason has 75 feet of wallpaper border she wants to put up a wallpaper border around his Rectangular bedroom that measures 12‘ x

Lerok [7]

Answer:

Jason reasoning is incorrect

Jason should have calculated the perimeter of the room instead of calculating the area

Step-by-step explanation:

we know that

The perimeter of the rectangular bedroom is equal to

$P=2(L+W)$

where

$L=12\ ft\\W=14\ ft$

substitute

$P=2(12+14)$

$P=52\ ft$

we have that

$52\ ft < 75\ ft$

Jason has enough border for the whole job

therefore

Jason reasoning is incorrect

Jason should have calculated the perimeter of the room instead of calculating the area

What number is in between 6534 and 6565

ahrayia [7]

Answer:

I am assuming any number in between these two, so let's just say 6,550.

Step-by-step explanation:

If you count up from 6,534, you will eventually get to 6,550. If you continue to count up, you will eventually reach 6,565 which is bigger than 6,550.
