Question

on a
number
line points P, Q and R such
that, d (P, R) = 15 d (R,Q) = 7
d (R,Q) = 7 and then
Find d (PQ).​ tell in urgent

Answer 1

Answer:

d(P,R) = d(R,Q) + d(P,Q)

15 = 7 + d(P,Q)

d(P,Q) = 15 - 7

d(P,Q) = 8 units

Hope it helps :)

Answer 2

Answer:

d(P,Q)=8

Step-by-step explanation:

As per the figure

d(P,R) =d(P,Q) +d(Q,R)

So 15=d(P,Q)+7

d(P,Q)=15-7=8
