Answer:

x = 3

angle B = 70 degree

angle C = 50 degree

Step-by-step explanation:

angle B + angle C = angle CDA ( exterior angle property)

(22x+4) + (15x +5) = 120

22x + 15x + 4 + 5 = 120

37x + 9 = 120

37x = 120- 9

37x = 111

x = [tex]\frac{111}{37}[/tex]

x = 3

angle B = 22x + 4

            = 22(3) +4

            = 66 +4

angle B = 70 degree

angle C = 15x+5

             = 15( 3) + 5

             = 45 + 5

angle C = 50 degree

Hope this helps.
