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!
