A) a = 12, b = 16, c = ? b) a = 15, b = ?, c = 18
c) a = ?, b = 6, c = 15
d) a = 4.1, b = 3.3, c = ?
e) a = ?, b = 6.5, c = 12.2

a)c=20

b)b=16

c)a=-3

d)c=2•5

e)a=0•8

ad = ae + ed = y + 7

similar triangles therefor

ac/ab = ad/ae

6/4 = (y + 7) / y

cross multiply

6y = 4(y + 7)

6y = 4y + 28

2y = 28

y = 14
