What would the answer be if the total was 23 in a math triangle sum stumper?

Answer 1

A triangle has 3 sides.

So,

3 x 23=69

If we add 1 to 9 the result is 45

So we have, [69-45=24] 24 less.

we can repeat three numbers. Those numbers will stay at the corner of the triangle.

As we have 24 less we have to see which numbers will make the sum of 24.

7+8+9=23

so,

side one): 7 _ _ 8

Side two): 8 _ _9

side three): 9 _ _7

Side 1:

7+8=15

23-15=8

so we need 8 more and,

5+3=8

side one is 7,5,3,8

side 2:

8+9=17

23-17=6

we need six more and,

4+2=6

side two is 8,4,2,9

side three:

9+7=16

23-16=7

we need seven more and,

6+1=7

side three is 9,6,1,7

there you go,

side one- 7,5,3,8

side two-8,4,2,9

side three-9,6,1,7
