Question

$area \: of \: triange \: with \: a = 8 \: b = 5 \: c = 5$

heron's formula​

Answer 1

Answer:

a=12√3

Step-by-step explanation:

s= a+b+c/2

=18/2

s=9

a=√9(9-8) (9-5)(9-5)

a=√9(3)(4)(4)

a= 3(2)(2) √3

a=12√3

Answer 2

Step-by-step explanation:

Triangle

Solve for side

a≈9.4

or

3.4

b Base

5

c Side

5

A Area

8

Using the formulas

A=√s(s﹣a)(s﹣b)(s﹣c)

s=a+b+c

There are 2 solutions fora

a=√b2+c2+2(bc)2﹣4A²=52+52+2·(5·5)2﹣4·82≈9.40312

a=b2+c2﹣2(bc)2﹣4A2=52+52﹣2·(5·5)²﹣4·82≈3.403
