458 divided by 31 using compatible numbers

14.77

458 / 31 = 14.77

It is actually a rational answer meaning it continues to go in terms (and doesn't stop) so I only included the smallest decimal degits in the answer.

14

Step-by-step explanation:

 31⟌458

     -0    

       45  

     -31  

       148

     -124

         24

the sum of all the angles in a triangle are equal to 180

so you can add   the 3 given angles together to equal 180:

5y + 2y + 2y = 180

or since all three angles have the same letter, combine the 3 angles to equal 180:

9y = 180

good luck on your studies! : )
