Answer:

Step-by-step explanation:

ABC right angled at B such that

BAC=2×ACB.

Let ACB = x

BAC = 2x

ABC = 90°

And the sum of angle in a triangle is 180°

:- x + 2x + 90° = 180°

Collecting like terms

3x = 180° - 90°

3x = 90°

x = 90/3

x = 30°

Angle ACB = x = 30°

Angle BAC = 2x = 2×30° = 60°
