PROBLEM SOLVING - #1

​Solution:

Hypotenuse CD ≅ JH

y + 50 = 6y

50 = 6y - y

50 = 5y

50 = 5y

5 5

y = 10

PROBLEM SOLVING - #1

​Solution:

Leg CB ≅ JI

3z = z + 18

3z - z = 18

2z = 18

2z = 18

2 2

z = 9

PROBLEM SOLVING #2

​Solution:

Hypotenuse KJ ≅ FH

49 = b + 43

49 - 43 = b

6 = b

PROBLEM SOLVING #2

​Solution:

Leg KI ≅ FG

c + 34 = 44

c = 44 - 34

c = 10
