Answer: 30°

Step-by-step explanation: The base angles of an isosceles triangle are equal, so m∠ACB = 75°.

The sum of the angles of any triangle is 180°.

75° + 75° + m∠BAC = 180°

m∠BAC = 180° - (75° + 75°) = 30°

The triangle is a sum of three non-collinear points. The sum of all the angles of the triangle is equal to 180-degrees.

The value of ∠BAC is equal to 30°

In the given image, the triangle is isosceles, in which two sides and two angles are equal.

Given, in triangle ABC, the measure of ∠ACB =  75°.

Now, we know that:

Sum of all the angles of triangle = 180°.

∠ABC + ∠ACB+ ∠BAC = 180°

75° + 75° +  ∠BAC = 180° [angles in isoceles triangle]

∠BAC = 180° - 150°

∠BAC = 30°

Therefore, the value of ∠BAC is equal to 30°
