⇒ Query:
⇒ In the ΔABC, if ∠ABC is 30° and ∠ACB is 90°. Find ∠BAC.
=========================================================
→ Solution:
Given,
In ΔABC,
∠ABC = 30°
∠ACB = 90°
To find the other angle, apply the angle sum property.
Angle Sum Property:
This theorem states that the sum of all angles of a triangle is 180°
In ΔABC,
∠ABC + ∠ACB + ∠BAC = 180°
30 + 90 + ∠BAC = 180
120 + ∠BAC = 180
∠BAC = 180 - 120
∠BAC = 60°
∴ The value of ∠BAC is 60°

Answer:
The sum of all the angles of a triangle is 180°.
The angles of the given triangle ABC are <ABC, <ACB, <BAC.
Given that:-
ABC = 30° and ACB = 90°
We have to find angle BAC.
Now,
BAC + ACB + ABC = 180°
BAC + 90° + 30° = 180°
BAC = 180 - 90 - 30
BAC = 60°
So the angle BAC is 60°.
