Question

IN AN ISOSCELES TRIANGLE THE VERTEX ANGLE IS 40
DEGREES WHAT IS THE BASE ANGLE OF TRIANGLE ?​

Answer 1

Answer:

70 is the only right answer

Answer 2

Step-by-step explanation:

since the angles opposite to the equal sides are equal, let the base angles be x.

by angle sum property,

x + x + 40° = 180°

2x + 40° = 180°

2x = 180° - 40°

2x = 140°

x = 140°/70°

x = 70°

therefore the two base angles are 70° each.
