The image you have provided contains a math problem in Gujarati. The question translates to:

"If the two angles of a triangle are equal, what will be the measure of the third angle?"

Options:

• A) 30°
• B) 45°
• C) 60°
• D) 50°

Solution:

For an isosceles triangle (where two angles are equal), the sum of all angles in any triangle is always 180°. Let the two equal angles be $x$. The equation will be:

$x + x + \text{third angle} = 180^\circ$

This simplifies to:

$2x + \text{third angle} = 180^\circ$

So, the third angle will be:

$\text{third angle} = 180^\circ - 2x$

We need to find the correct third angle from the options provided.

If we take $x = 60^\circ$, then:

$\text{third angle} = 180^\circ - 2 \times 60^\circ = 180^\circ - 120^\circ = 60^\circ$

So, the correct answer is C) 60°.
