Lynn cut a whole pie into wedges with angles measuring 90°. How many wedges did she cut the pie into?

4 wedges

Step-by-step explanation:

We can assume the whole pie is shaped like a circle. There are 360 degrees in a circle.

She cut wedges with 90 angles. To find how many wedges, we can divide the total number of degrees by each wedge's number of degrees.

total/wedge

360/90=4

So, she cut 4 wedges

4

if there are 360 degrees worth of pie then we just divide 360 by 90 getting 4
