Easy. Each slice of the cheese pizza will have a 45-degree interior angle; each slice of the pepperoni pizza will have a 72-degree interior angle; and each slice of the mushroom pizza will have an approximately 51-degree angle.
It’s nice when teachers use real life examples to teach a subject.BUT NOBODY IN THEIR RIGHT OR LEFT MIND WOULD SLICE A PIZZA INTO AN ODD NUMBER OF SLICES!!!!!
A lot of overthinking being done here … the interior angles of all triangles add up to 180 degrees, regardless of the “number of slices” cut or size of triangle.The interior angles of each piece will be 180 degrees, Paige.
Ummm…..no one slices pizza into odd-numbered slices. But I suppose it’s OK to pretend for the math lesson. And certainly not rocket science. The first is 45 degree angles. The second is 70 degrees. And the last is 51.428571 degrees. Although, if you really think about it, how often does a pizza place ever slice the pizza into completely equal slices? I always get pizzas where there are somewhat skinny slices as well as wide. But I CAN tell you that opposing slices are equal!
Paige gives a LITERAL (and correct) answer to the question: “How many degrees will the interior angles of each slice be?” If the oven temp. is set to 350 degrees, then that will be the temperature of each slice as well, including the interior angles.
A chain restaurant in Philadelphia, Pennsylvania sued to cut pies onto 5 equal slices, using a cutting guide. Do they make pizza pie sized cutting guides?
You all who think the answer is based on triangles haven’t caught the trick in the question. THESE ARE NOT TRIANGLES. They’re sections of a circle. A radial line on a circle is ALWAYS 90° from the edge. Therefore, each slice has two 90° angles plus whatever is the angle at the center vertex (360/8, 360/5, or 360/7).

I think the math teacher is doing that on purpose.

Gee, I figured any question asked of Peter involving pizza he’d get right automatically.

Impossible to give a correct answer to all 3 questions, simply, because the statements are incomplete. “Equal parts” is missing in all of them.

Pizza place by me cuts 12 slices to a cheese, 10 for a two topping pie, and eights for more than two topptings.

I don’t know anybody who can accurately slice a pizza into fifths, let alone sevenths.

45º, 72º and 51.42º….

I am guessing the question asks the sum of the interior angles of each slice, which is always 180 degrees regardless of the size of angles themselves.

Much easier in radians. π/4, 2π/5, and 2π/7.

=131/280 exactly
you act proud of your factional ignorance.Did not any of you pass the 5th grade?1/8 + 1/5 + 1/7 =(5*7)/(8*5*7) + (8*7)/(8*5*7) + (8*5)/(8*5*7)=131/280
There are three-3 kinds of people in the world,those who know math and those who don’t.

Ajax,
actually there are 10 kinds of people… those who know binary and those who don’t.Alberta Oil Premium Member over 8 years ago
Depends.. on who is cutting the pizza. It will be equal parts if.. the person cutting is NOT the one to pick the first piece.

We call those unevenly-sized slices, “Family Cut”. Big pieces for the adults, little pieces for the kids.

Does it say to add the interior angles together? No? Then it is asking for, a=x b=y and c=z, not a+b+c=180.
