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.
