Answer:
1) AC = 5cm
2) PC = √194 cm
Step-by-step explanation:
1) If triangle ABC and PQC are right angles at B and Q respectively.
Then, by Pythagoras theorem
in triangle ABC,
AC² = AB² + BC²
= 16 + 9
=> AC² = 25
=> AC = 5cm
in triangle PQC,
PC² = PQ² + CQ²
= 169 + 25
= 194
=> PC = √194 cm
these are the answers
I hope this helps
