Question

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

Answer 1

Answer:

triangle is having only 3 sides but you asked to find 4th side in the question I think you typed your question wrongly

Answer 2

Step-by-step explanation:

Given,

Semi perimeter of triangle, S = 13

a = 8

b = 7

c = ?

We know that semi perimeter of triangle is:

[latex]S=frac{a+b+c}{2}[/latex]

a + b + c = 2S

8 + 7 + c = 2 x 13

c = 26 – 15 = 11

Therefore, the value of c is 11.
