Answer:
6 cm
Step-by-step explanation:
If you use Tangent-secant product (chapter reference), AB/AC = AD/AB so 4/2 = AD/4. AD = 8, CD = AD - AC = 8 - 2 = 6 cm.
You put 6 on one side then equal it to 9 with at variable of "X" with it multiplied by 3 to make the thing an equation
Sum of angle in a triangle is 180, so 33+70+x=180
x=77
x and y are vertical angles so y=77
