Question

ABC is an obtuse angled isosceles triangle. If AB=AC and one of the equal angles measures 30°. find the measure of other two angles.​

Answer 1

Answer:one of the equal angle=30

Another angle=30

Third angle=180-(30+30)

=180-60

=120

Step-by-step explanation:

Answer 2

Step-by-step explanation:

Equal ang. = 30° and 30°

Let 1 angle be x

Sum of ang. of a triangle = 180°

x + 30° + 30° = 180°

x + 60° = 180°

x = 180° - 60°

x = 120°

x = 120°
