To find RT, we first need to find the radius of circle P. Since the diameter is 24 inches, the radius is half of that, which is 12 inches.
Next, because ∆TR is an equilateral triangle (all angles are 60 degrees), each side is the same length.
Since RT is a radius of circle P, RT is also 12 inches.
Therefore, RT is 12 inches.
The closest answer choice is 12 inches.
∆TRI is inscribed in circle P whose diameter is 24 inches, and m∠I
= 60°.
