Question

Find the value of k. Give your answer in degrees ().
k
84°
Not drawn accurately

Answer 1

Explanation:

I had to add some assumed portions to your posted picture. See image.

The yellow boxed angle is 84 degrees (upper LEFT) due to alternate interior angles of parallel lines transected by another line.

then, since the triangle is isosceles ....the other (lower LEFT) angle is 84 degrees also....

that means that k= 12 degrees for the triangle interior angles to sum to 180 degrees .
