Given that t<span>riangle QST is isosceles, and bisects T, the line bisecting T also bisects QS.
A line that bisects the other angle of an isosceles triangle,</span> bisects the opposite line at right angle. Therefore, since triangle <span>QST is isosceles, and bisects T, the line bisecting T bisects QS at R and then QRT = SRT = 90 degrees.
QRT cannot be equal to STQ since an isosceles triangle does not have a right angle as QRT is a right angle.
2*RTQ is equivalent to STQ, and it has been established that QRT is not equal to STQ. Thus QRT is not equal to 2*RTQ.
QRT </span><span>cannot be equal to RTQ since an isosceles triangle does not have a right angle as QRT is a right angle.
Therefore, the true statements about QRT is QRT = SRT.</span>
D=110
t=50
r=x
solution
110=50x
x=110/50
x=1hr. 20mins
or
x=1 X 20/60
x=1 1/3 hr
C = 2 x pi x r
divide each side by 2 x pie to get r by itself.
45/(2(3.14)) = r
r = 7.17
