Question

Pls ans the below questions

Answer 1

Step-by-step explanation:

6.a) As it is a right angled triangle,

Option (iii) will be the answer.

1/2 * base * height.

b) As per Pythagoras theorem,

(AO)² + (BO)² = (AB)²

=> 12² + 5² = (AB)²

=> 144 + 25 = (AB)²

=> 169 = (AB)²

AB = 13.

Option (ii) will be the answer.

c) Option (i) will he be the answer .

d) Area of triangle ABC = √s(s-a)(s-b)(s-c)

Here, s = (ab+bc+ca)/2 = 13+14+15 i.e. 42/2 = 21.

Now, putting the values in formula, We get

√21*(21-13)(21-14)(21-15)

= √21*8*7*6

= 84 cm².

Options seems to be wrong for last question.

Hope you will find it helpful.
