Remember the divisibility rule for 9. The sum of the digits of the number must be divisible by nine. 
Let the digit be x. Then x+3+5+2+0=x+10 has to be divisible by nine. Recalling that 18=9*2, we note that x=8.

Two angles of a triangle measure 22 and 53 what is the measure of the third angle
Musya8 [376]
The third angle is 105.
How do I know this?
Add 22 and 53:
22 + 53 = 75
All interior angles on a triangle should add up to 180.
Subtract 75 from 180:
180 - 75 = 105
105 is our answer.
Hope this helps! =)

Turn 7/16 into a percent
kramer
To do this first we will take the fraction and turn it into decimal form. To do this we will divide the numerator and the denominator. 

7 ÷ 16 = <span>0.4375

Now to take it to percent form we will multiply by 100.

0.4375 </span>× 100 = 43.75%

So, 7/16 turned into a percentage would be 43.75%

Hope I helped ya!!
