Question

Find the value of c if in a triangle S=13,a=8,and b=7.​

Answer 1

Answer:

Correct answer of c = 11c=11

Explanation:

Given that,

Semi perimeter of triangle (S) = 13(S)=13

a = 8a=8

b = 7b=7

c =c= ?

As we know that,

Semi perimeter of triangle(Hero's formula) S = \frac{(a+ b +c)}{2}S=

2

(a+b+c)

a+ b +c = 2Sa+b+c=2S

8 + 7 + c = 2\times138+7+c=2×13

Correct answer of c = 26 - 15 = 11c=26−15=11
