Answer:

x= 4

m<ABC= 56

Step-by-step explanation:

since BD bisects, both sides of the angle are equal.

So we can set up an equation like this: <ABD=<CBD

(9x-8)=(5x+8) calculate for x

you'll find x=4

then put four into one of the angle equations

9(4)-8=28

now we know each side of the angle is 28, double it to find the whole (<ABC)

28+28=56
