Question

if a right triangle ABC,∆b=90,ab≠6cm BC=8cm , find ac
​

Answer 1

Answer:

10

Step-by-step explanation:

For triangle ABC by using Pythagoras theorem

we can write

AC^2=AB^2+BC^2

=(6)^2+(8)^2

=36+64

AC=√100

AC=10

Answer 2

Answer:

∆ ABC is right -angled at B.

Therefore , by applying Pythagoras

theorem ,we obtain

AC2= AB2+BC2

AC2=(6cm)2+(8cm)2

AC2 =(36+64)2cm =1002cm

AC

(√100)cm=(√10×10)cm

AC=10cm
