Question

In triangle ABC angle B=90 degree,AB =5cm and BC =12cm find Ac
​

Answer 1

Answer:

by Pythagoras property absq.+bcsq =acsq

12sq.=144 5sq.=25

144+25=169=13sq.

So ac=13

Answer 2

Answer:

13

given:

angle B=90°

so it is a right angled triangle

AB=5m

BC=12cm

Step-by-step explanation:

by Pythagoras theorem

AC^2=AB^2+BC^2

AC^2=5^2+12^2

AC^2=25+144

AC^2=139

AC=√139

AC=13
