Answer:
a/sinA = b/sinB = c/sinC
Step-by-step explanation:
Simple drawing shows that measure interior angle at B is 25 degrees.
Easily seen from a drawing are that measure of angle CBD is 25 degrees, and measure of angle CAD is 65 degrees (which was already given).
Heres the plot formula!
C because when you add 2 in one column you keep adding three to the other
