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°
