Question

the figure below shows a circle with center s, diameter lj, secant li, and tangent fz. which of the angles must be right angles? select all that apply. answer attempt 1 out of 2 ∠fjs ∠sfx ∠flk ∠lsf ∠lfj ∠lfx

Explanation:

Step1: Recall tangent - radius property

A tangent to a circle is perpendicular to the radius at the point of tangency.

Step2: Identify relevant angles

Since $FZ$ is a tangent and $SF$ is a radius, $\angle SFX = 90^{\circ}$.

Answer:

$\angle SFX$
