15. Triangle ABC is an isosceles
triangle in which angel C=90 degree.
If AC =6cm, then AB=
O 672 cm
O 6 cm
412 cm
O 2v6 cm​

Answer 1

Answer:

6√2 or 72 cm

Step-by-step explanation:

Given: In an isosceles AABC, C = 90°, AC= 6 cm.

To find: AB

Soution

In an isosceles AABC, ZC = 90°,

Therefore, BC = AC = 6 cm

Applying Pythagoras theorem in AABC, we get

ABP = AC² + BC²

ABP = 62 + 62(AC = BC)(Side of isosceles triangle)

ABP = 36 + 36

AB = 72

AB = 6√2cm
