1.	In an isosceles triangle each of its base is 40 degree then what is the value of its vertex angle
Answer» ong>Answer: Also, as in all triangles, the sum of the ANGLES is 180° . We can then solve for x and determine that 3x+60=180 , which LEADS to 3x=120 and finally x=40 , so the vertex angle is 40° and each base angle is 70° . Hope it HELPS....
