    I've completed your sketch such that you have 2 right triangles, marked in grey.

    I've marked the right angles with a red dot. The opposite angles which are equal are marked with a green dot.

    Use the property that the interior angles of a triangle add up to 180.

    Both have right angle that's why both are same.
