If ∠t is inscribed in a semicircle, then the measure of angle t degrees.
a)180
b)0
c)360
d)90

Option D) 90°

Step-by-step explanation:

It is given in a circle with center O, triangle TBC is formed in a semicircle.

We know If ∠ O is the angle formed at center, ∠T will be half of the measure of central angle O. (inscribed angle conjecture)

∠ T = of ∠O

=

Therefore, measure of the angle inscribed in a semicircle will be 90°

Option D). 90° is the correct option.
