Question

In circle S below, what type of angle is < RST? ( choose: central, interior, exterior, inscribed, chords)What type of angle is < RUT? (choose: interior, inscribed, exterior, central, tangent)If the measure of < RST = 70°, then what is the measure of < RUT? ( choose: 140, 35, 50, 70)

Answer 1

$\angle\text{RST}$

is a central angle.

If:

$\begin{gathered} \angle RST=70 \\ \angle RUT=\frac{70}{2}=35 \end{gathered}$

∠RUT is an inscribed angle
