John has a box of nails. The box contains 65 small nails, 40 medium nails, and 45 large nails. Susan has a box of nails that has the same proportion of small, medium, and large nails as John's box. There are 176 medium nails in Susan's box.
What is the total number of nails in Susan's box? Enter the answer in the box

Susan has a total of 660 nails

Step-by-step explanation:

John box contains 65 small nails, 40 medium nails, and 45 large nails.

The proportion of John nails is

65/5:40/5:45/5

13:8:9

Total = 30

If Susan has 176 medium nails and same proportion to John's nails

8/30(x) = 176

Where x is the total number of nails for Susan box

X= (176*30)/8

X= 22*30

X= 660 nails

Susan has a total of 660 nails

according to the triangle sum theorem, all the angles in a triangle must add up to 180 degrees. if we know one angle is already 90, we do 180-90=90. the other 2 angles must add up to 90, exactly.
