In figure angle bac 90
WebSolution: Given, ABC is a triangle. Also, ∠BAC = 90°, AD ⊥ BC and ∠BAD = 50°. We have to find the measure of ∠ACD. By angle sum property of a triangle, We know that the sum of all the three interior angles of the triangle is equal to 180 degrees. Considering triangle ABD, ∠ADB + ∠ABD + ∠BAD = 180°. 90° + ∠ABD + 50° = 180°. WebIn figure DEFG is a square and ∠BAC=90 o.
