Answer:
24 + 72 = 96
Step-by-step explanation:
20 + 70 = 90
4 + 2 = 6
90 + 6 = 96
You can first add the ones and then add the tens start always from the ones place gradually getting the higher value digit, to make it easier stack them.
72
24
+____
96
If you are describing a quadrilateral, then the answer is
m1 + 73 + 107 + 92 = 360
m1 + 272 = 360
m1 = 360 - 272
m1 = 88 degrees.
If it is anything but a quadrilateral, it would be a good idea to state what it is.
