6 0

You can narrow down 258/300 to 43/50 by dividing both sides by 6 to make it easier. Now, if you divide 43 by 50 you should get a decimal of .86, which is also 86%.

PLEASE HELP ME!

arlik [135]

Answer:

Angle: 22.5 deg, Complement: 67.5 deg, Supplement: 157.5 deg

Step-by-step explanation:

22.5 is 1/3 of 67.5

so compliment is 67.5.

Supplement is just adding another angle so I chose 7.

I did 22.5 x 7 = 157.5

Another example would be:

Angle: 10 deg, Complement: 30 (because 10 x 3), Supplement: 70 (because 10 x 7)

Hope this helps :)
