Find the remaining angles and side if they exist. If no triangle exists, say "No triangle"

a= 4 b=1 y=100 degrees

Please help!

GIVE US SOME MORE INFO...THE ANGLE Y=100 DEGREES IS A CORESPONDING ANGLE OR THE ANGLE FORMED BY THE TWO SIDES a and b?

Anyway if the angle is the one formed by the two sides a and b yes there is triangle...

get the cosine rule to find the 3rd side and then apply again the cosine rule to find the other two angles...

as simple as such . good luck
