What is a?
Find remaining angles and side if they exist. If no triangle exists, say "No triangle"
a=4 a=1 y=100 degrees
(the problem does not state where angle y lies) please solve and explain process I am doing a similar problem but found this one in the book.
If y is the angle between sides a and b then you can find the third side by using the "cosine law":
You can then find the angle opposite, say, a, using the "sine law":
.
If angle y is NOT between the two sides, then there is no such triangle.
