To do this you must divide the two numbers -23÷45 is -0.511111....
Evaluating 3^3/2 gives us 5.196152423, so we can round this to 5.
3/5 is smaller then 3/4(you can tell from denominators) 5/8 is smaller then 3/5, and 7/4 is greater then 1, so the only logical one is C. Hope this helped!
Answer:

Step-by-step explanation:
An isosceles triangle has two equal sides and the two opposite angles to the sides to be equal.
Given that; RP = RS, RQ and PS are common,
RP = SQ (opposite sides of parallelogram RPQS)
PQ = RS (opposite sides of parallelogram RPQS)
ΔRPS = ΔQPS (congruence property)
Thus comparing triangles PQR and SQR,
=
(similarity property)
<PRS = <PRQ + <SRQ (bisection of included <PRS)
<PQS = <PQR + <SQR (similatity property to <PRS)
=
(congruence property)
But, SRQ = PQR
So that;
Therefore by Side-Angle-Side (SAS), the required additional fact is:
You're correct with the answer you have selected. It's 7.2 x 10^7
