Question

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

Answer 1

s= a+b+c/2 then 26= 8+7+c

c= 26-15

c=11

Answer 2

Solution:

AnswEr:-

• The required value of c is 11.

Given:-

• In a triangle S = 13, A = 8, B = 7

Find Out:-

• The required value of c = ?

Required Explanation:

• S = 13
• A = 8
• B = 7

Formula used:-

• S = a + b + c/2

Putting the values according to the given formula:-

$\leadsto \sf {13 = 8 + 7 + \dfrac{C}{2}}$

$\leadsto \sf {13 = 15 + \dfrac{C}{2}}$

$\leadsto \sf { 13 \times 2 = 15 + C}$

$\leadsto \sf {26 = 15 + C}$

$\leadsto \boxed{\sf{\purple{11 = C}}}$

Therefore:-

• The required value of C is 11.
