Answer:
c. 24
Step-by-step explanation:
Triangle PQR has dimensions that are a factor of 45/15 = 3 times those of triangle ABC, so side QR will be 3 times the length of side BC:
3·8 = 24 . . . . . matches choice C
_____
We are not given any information that says the triangles are similar. We have assumed they are. Without that information, there is no basis for working the problem.
Mark can:
7*6=42
then just add back the 4 zeros
so its 42 0000
Answer:
Equation of line l,
3x-4y=1/2
y=3/4x-1/2
we get,
slope of line l =3/4
Equation of line m,
x-5=2y
y=1/2-5/2
Hence slope of line m=1/2
Slope of line l is not equal to slope of line m. Hence the line are not parallel.
Slope of line l* slope of line m ,
(3/4)*(1/2) =3/8
Since the product of slope of line l and the slope of line m is not equal to -1, the lines are not perpendicular.
Hence the lines are neither perpendicular nor parallel..
