Answer:
\angle ACB=40^{\circ}, \angle ABC=63^{\circ}
Step-by-step explanation:
Finding x:
We know that 
, because it's a straight line. So, 
.
We know that the sum of the angles of any triangle will be 
.
So, we have that 
.
Combining like terms on the left gives 
.
Subtracting 
from both sides gives 
.
Dividing both sides by 
gives 
.
Finding missing angle measures:
.
.
So, 
and 
and we're done!
Note: 
. Coincidence? If not, try and prove it!
