this is it hope this will help u

Answer 2

The ∠BAC will have a value of 120°.

Given:

It is an isosceles triangle.

The value of ∠ABC = 30°

The sides of the triangle BA = AC

To Find:

The value of ∠BAC

Solution:

It's fairly simple to find the answer to this question, as seen below.

Consider an isosceles triangle ABC.

An isosceles triangle is a distinct kind of triangle with two equal sides and two equal-sized angles on the opposite sides of the equal sides.

From the definition and the given data,

The sides of the isosceles triangle BA are equal to AC, and the angles opposite to this side will also be equal.

That is,

BA = AC

∠ABC = ∠ACB = 30°

We know that,

The sum of all the angles of any triangle is equal to 180°

That is,

∠ABC + ∠ACB + ∠BAC = 180°

On substituting the given values,

30° + 30° + ∠BAC = 180°

60° + ∠BAC = 180°

Therefore,

∠BAC = 180° - 60°

∠BAC = 120°

Hence, the ∠BAC will measure at 120 degrees.
