you need to find the side of a knowing the base angles of the isosceles triangle. 

hope this helps.

idk what they equal. im not good with finding angles or side degrees... thanks for the picture

anonymous · Answer

or do you just add them both up?

anonymous · Answer

which =112 degrees

campbell_st · Answer

ok... so the angles in a triangle add to 180 

so 

a = 180 - 56 - 56

ohhh! okay thanks os much :)
