Question

Plz solve all the specially the 1st one if possible I need this its urgent. (･ิω･ิ)​

Answer 1

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

Answer 2

these are the answers

I hope this helps
