Answer: <em>A. 241 feet</em>
Step-by-step explanation:
<em>The figure shows two rectangular triangles. </em>
<em>These triangles are similar since they have two identical angles: </em>
<em>the first angle is 90 degrees; </em>
<em>the second angle is equal because the law of reflection states that the angle of incidence is equal to the angle of reflection. </em>
<em>The law of reflection states that the angle of incidence is equal to the angle of REFLECTION.</em>
<em>Let's make the proportion:</em>

<em>It takes a minimum of 100 feet for a parachute to open and safely land without injury, so:</em>
<em>341.25 - 100 = 241.25 (feet)</em>
<em>241.25 ≈ 241 (feet)</em>
