Ihave been confused with rounding to 3 decimal places with more than 2 over 5 numbers (if that makes sense)

e. g: 4.4965 rounded to 3 decimal places.

if anyone could show me how to do this i would appreciate it.

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

when studying polynomials, you often hear the terms zeros, roots, factors and x x the multiplicity of a zero is important because it tells us how the graph of the let's look at the graph of a function that has the same zeros
