Assertion (A) : $\triangle ABC \sim \triangle PQR$ such that $\angle A= 65^\circ, \angle C = 60^\circ$. Hence $\angle Q = 55^\circ$. Reason (R): Sum of all angles of a triangle is $180^\circ$

Directions : In question below a statement of Assertion (A) is followed by a statement of Reason (R). Choose the correct option : 

### Given:
Assertion (A): $\triangle ABC \sim \triangle PQR$, and given angles:

$ \angle A = 65^\circ, \quad \angle C = 60^\circ $

We need to determine whether $\angle Q = 55^\circ$.

### Step 1: Find $\angle B$
Since the sum of the angles in a triangle is $180^\circ$:

$ \angle B = 180^\circ - (\angle A + \angle C) $

$ = 180^\circ - (65^\circ + 60^\circ) $

$ = 180^\circ - 125^\circ $

$ = 55^\circ $

### Step 2: Find $\angle Q$
Since $\triangle ABC \sim \triangle PQR$, their corresponding angles are equal:

$ \angle A = \angle P, \quad \angle B = \angle Q, \quad \angle C = \angle R $

Thus, $\angle Q = \angle B = 55^\circ$, which verifies the assertion.

### Step 3: Verify the Reason
The reason states that the sum of all angles in a triangle is $180^\circ$, which is a fundamental property of triangles.
