Marked(10)/total = 3/20 (from sample)
total/10 = 20/3 (inverting the above proportion)
total = 10•20/3 = 200/3 ≈ 67
Divide both numbers in one of the ratios by their highest common factor. This will give you the scale factor of the bigger triangle to the smaller triangle.
35+25=60
y=60
If you add the opposite side values of the triangle (not the one touching the y), you get the value of y). 35+25=y
This works because y+x= 180 and the three angles of a triangle add to 180.
