And also explain it.​

Answer 1

Answer:

10m

Step-by-step explanation:

p=PB

b=AP

h=√(20^2+21^2)

h=√(400+441)

h=√841

h=29

h=PQ+QB

29=PQ+19

PQ=29-19

PQ=10m

Answer 2

Step-by-step explanation:

h= underroot 20 square + 21 square

h= underroot 400+441

h= underroot 841

h= 29

h=PQ+QB

h is 29 so

29=PQ+19

PQ=29-19

PQ=10m distance
