In an isosceles triangle, the base angles are equal. The vertex angle is 40°. What are the base angles of the triangle? (Remember, the sum of three angles of a triangle is 180°).

Answer»

Step-by-step explanation:

let the base ANGLES be X...

In triangle ABC

40 + x + x = 180

40 + 2X. = 180

2x = 140

x = 70

base angles = x = 70.....

HOPE it is correct
