Answer 2

Answer:

Correct answer is option B i.e. 50 degree.

In given figure, the measure of ∠BAC is 50°.

Step-by-step explanation:

In a triangle if two sides are equal, then the angles opposite to the same two sides are also equal.

So, as given in the figure

AC= BC = 5 cm

So,

∠BAC = ∠CBA = 50°

( ∠BAC is opposite to side BC and ∠CBA is opposite to side AC)

∠BAC = 50° = 2x + 20°

2x=50°- 20° = 30°

x = 15°

We know that,

∠BAC +∠CBA + ∠ACB = 180°

(The sum of all angles are triangle is 180°.)

50°+ 50°+ ∠ACB = 180°

∠ACB = 180° - 100°

∠ACB = 80°
