Question

what is the vertex? options: k, j, l (with a triangle labeled j, k, l and an 82° angle at l)

Explanation:

In a triangle, a vertex is a point where two sides meet, and an angle is formed at a vertex. The angle of \(82^\circ\) is at point \(L\), so \(L\) is the vertex of that angle. Also, visually, in the triangle \(JLK\), the angle is marked at \(L\), so the vertex for that angle (or the vertex we are looking at here) is \(L\).

Answer:

C. L (assuming the options are labeled with K, J, L as per the buttons, so the correct option is the green button with L)
