Find the unknown value if two shapes below are similar

➷ 4) Find the scale factor:

30/18 = 5/3

5/3 = scale factor

x:

25/(5/3) = 15

y:

15 x (5/3) = 25

z:

115/(5/3) = 69

x = 15

y = 25

z = 69

5) There won't be a scale factor for this one because they are congruent

16x = 112

Divide both sides by 16:

x = 7

3(7) + 5y = 41

21 + 5y = 41

Subtract 21 from both sides

5y = 20

Divide both sides by 5:

y = 4
