Answer:

Sam sliced the pie into 15 equal slices

Step-by-step explanation:

Given : Sam cut a pie into equal slices.There are only three slices left.The angle measure for the three slices is 72 degrees.

We have to determine the number of slices that the Sam cuts.

Sam cuts a pie and pie is in shape of circle therefore total angle measure is 360°.

Since, Given the angle measure for the three slices is 72 degrees.

So, The angle measure for the one slices is $\frac{72}{3}=24$ degrees.

Since, Pie is cut into equal slices.

So, measure of each slice must be equal.

So let he cut x slices of pie of 24°

So , total measure of x slices must be equal to 360°

24 · x = 360

x = 15

Thus, Sam sliced the pie into 15 equal slices

10 white

altogether the is 30 marbles so that means it is 'out of' 30

and because the is 5 red it would be 5/30

and because the is 10 white it would be 10/30

that should be the answer but if you have to work the total all together then it would be 15/30

Please help I’m struggling

gulaghasi [49]

Answer: B, x=20; angle measure is 30°.

Step-by-step explanation:

Opposite angles are always the same.

You can see that 30° and 3x are opposite angles therefore 3x=30°.

In algebra, when a letter and a number are next to each other, it means times.

So, 3x=30° means 3 times something equals 30.

And we know that 3×10=30 so, x=10.

Hope this helps :)
