Answer:
295.31
Step-by-step explanation:
AC and AB are tangents to circle O, meaning that the angles C and B are right angles of 90 degrees. Since a quadrilateral's internal angles must sum up to 360 degrees, this means that A + B + C + O = 360
70 + 90 + 90 + O = 360
O = 110 degrees.
Answer:
B. 26.65
Step-by-step explanation:
QRST is a parallelogram
so
QR = TS = 7
and
QT = RS = √[(6)^2 +(2)^2] = √40 = 6.3246
So the perimeter of parallelogram:
= 2(7) + 2(6.3246)
= 14 + 12.6492
= 26.65
Answer is B. 26.65
Step-by-step explanation:
4 administrator are eligible and the student relations committee has only 2 administrator there are C (4,2) ways of choosing the administrators for the student relations committee
similarly for faculty members ways (8,3) and for students C (20,5)
the number of possible committee = 4!/2!2! × 8!/3!5! ×20!/5!15!
= 6 ×56 ×15504
= 5,209,344
