Answer:
C
Step-by-step explanation:
Draw in <QOS. That's the central angle. It is also 60 degrees.
<R which has Q and S as its end points, = 1/2 the central angle (always) so <R = 30 degrees.
C
Answer:
b. -3
Step-by-step explanation:
i hope this helps :)
Numbers are x and y
x is 5 more than y
x=5+y
product is -3
xy=-3
solve
sub 5+y for x since x=5+y
(5+y)y=-3
5y+y^2=-3
add 3 to both sides
y^2+5y+3=0
use quadratic formula where
ay^2+by+c=0
y=
a=1
b=5
c=3
y=
y=
y=
y=
or
the second number is 5 more or 10/2 more
add 10/2 to each
x=
or
the numbers are
and
or
and
aprox
the numbers are
-0.697224 and 5.967224 or
-4.302775 and 0.697224
