Answer:
Step-by-step explanation:
The area of a full circle is
A full circle has a central angle of 360 degrees.
The area of a sector is a fraction of the area of a full circle and is proportional to the central angle of the sector.
For a sector:
where n = central angle of sector.
Here you have a radius of 10 and a central angle of 120 deg.
Answer:
(B) The measure of angle SUT is equal to 90 degrees
Step-by-step explanation:
It is given that in In triangle STU, .
We can see from the triangle and also the given condition that the triangle will be right triangle as it is satisfying the Pythagoras theorem.
that is:
where u is the hypotenuse, s is the base and t is the perpendicular.
Thus, the angle SUT should be of 90°.
Thus, The measure of angle SUT is equal to 90 degrees.
Hence, option B is correct.
