Question

find x in each of the following figure

Answer 1

Answer:

Angle BAC= 60 Degrees

Step-by-step explanation:

Exterior angle=120 degrees

And 2 opposite sides are equal.

Therefore

Angle ABC + Exterior angle = 180 degrees

Angle ABC = 180-120

Angle ABC = 60 degrees

Angle ABC = Angle ACB (Angles opposite to equal sides are equal )

Angle ACB=60 degrees

Angle (ABC+ACB+BAC) = 180 degree

Angle BAC = 180- (60+60)

Angle BAC = 180-120

Therefore

Angle BAC = 60 degrees

⇒ ABC is an equilateral triangle.
