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>
Answer:
14x² - 37x + 5
Step-by-step explanation:
Use FOIL (First, Outer, Inner, Last):
That's your answer.
The events are independant (i.e. what she rolls on the cube has no impact on how the spinner works). The probability of two independant events is given by:
For the cube, 1/2 the numbers meet our requitment of being even, so:
For the spinner, there are 3 odds out of 5 (1, 3 & 5) so:
and then:
