Question

6. In right angle triangle ABC. ZB = 90°. seg AB = 8 cm, seg BC = 6 cm then find length of seg BD. 1) 4 cm 2) 4.8 cm 3) 10 cm 4) Can't be determined.

Answer 1

don't give me thanks

the formula of a triangle is 1/2 × hight + base

Answer 2

Answer:

Correct answer is 3) 10 cm

Step-by-step explanation:

Given,

In ΔABC, ∠B = 90°  { ∴ ΔABC is a right angled triangle }

AB = 8 cm

BC = 6 cm

AC = ?

Now, by using Pythagoras theorem:

⇒  AC² = AB² + BC²

⇒  AC = √AB² + BC²    

By putting the values we get:

⇒ AC = √(8)² + (6)²

⇒ AC = √ 64 + 36

⇒ AC = √ 100

⇒ AC = 10

∴ AC is 10 cm
