Answer 2

Answer:

1) BC = 26 cm

2) X = √13 cm

3) RQ = 12 cm

4) AC = 10 cm

Step-by-step explanation:

1) Given AC = 10 cm

AB = 24 cm

by Pythagoras theorem= > BC² = AB²+AC²

BC² = (24)²+(10)²

BC² = 576 + 100

BC² = 676=> BC = √676 = 26 cm

hence BC = 26 cm

2) given PR = 17 CM, RQ = 14 CM

By Pythagoras theorem PR² = PQ² + RQ²

238 = X² + 225

X² = 238-225 = 13

X = √13

3) given PQ = 35 cm, PR = 37 cm

by Pythagoras theorem PR² = PQ² + RQ²

1369 = 1225 + RQ²

RQ² = 1369-1225 = 144

RQ = √144 = 12 cm

hence RQ = 12 cm

4) given AB = 8 cm, BC = 6 cm

by Pythagoras theorem AC² = AB² + BC²

AC² = 64 + 36

AC² = 100=> AC = √ 100 = 10cm

hence AC = 10 cm
