Triangle IUP has angles I=50, U=60, P=70. What side is the longest side of the triangle?

IU

UP

IP

If triangle IUP has angles I=50, U=60, P=70. The longest side of the triangle would be IU because if you draw the triangle and put the amounts of the angles in the correct place you draw a line across from the biggest angle to the side across from it and that gives you the longest side

The longest side of the triangle is the opposit of the largest angle

so it is opposit to angle P

and the longest side is IU
