Remember that all the interior angles of a triangle add up to 180°.
The picture tells us two of the angles,
![\angle R](https://tex.z-dn.net/?f=%5Cangle%20R%20)
which is 40° and
![\angle T](https://tex.z-dn.net/?f=%5Cangle%20T)
which is also 40°.
Subtract the measurement of these two angles from 180° to find the measure of the third angle,
![\angle RST](https://tex.z-dn.net/?f=%5Cangle%20RST%20)
:
180° - 40° - 40° = 100°.
The measure of angle RST is 100°.

Answer: 100°
A) Linear velocity, v = ωr ω = Angular velocity, r = radius.
ω = 5 revolutions per minute. 1 minute = (1/60) hour.
= 5*2π radians / (1/60) hour = 600π radians per hour π = 3.14
= 600*3.14 = 1884 radians / hour
but radius, r = 10 feet, 5280 feet = 1 mile, 10 feet = (10/5280) mile
Linear velocity, v = ωr
v = 1884 radians / hour * (10/5280) mile
v ≈ 3.568 miles / hour
