It looks like you've provided an image of a triangle with labeled angles $a$, $b$, and $c$, and you are required to find their values.

Since this is a triangle, we can use the angle sum property of triangles, which states:

$\text{Sum of the angles in a triangle} = 180^\circ$

Therefore:

$\angle a + \angle b + \angle c = 180^\circ$

However, the specific values of the angles depend on additional information, such as whether the triangle is equilateral, isosceles, or if you are given any particular angle measurements. Can you confirm if this is a special triangle or provide more details about the angles?

Would you like further clarification or assistance on this?

Here are five related questions:

1. What is the angle sum property of a quadrilateral?
2. How do you calculate the angles of an isosceles triangle?
3. What is the difference between an equilateral and a scalene triangle?
4. Can you solve for angles in a triangle if only side lengths are known?
5. What is the relationship between exterior and interior angles of a triangle?

Tip: In any triangle, the largest angle is opposite the longest side!
