Question

Third angle of
45°
35°
70°​

Answer 1

Area T= 670.82
Perimeter= 150
Semiperimeter= 75


1. Input data entered: sides a, b, and c.
a=45
b=35
c=70

2. The triangle perimeter is the sum of the lengths of its three sides
p=a+b+c=45+35+70=150

3. Semiperimeter of the triangle

s= p/2 = 150/2= 75

4. The triangle area using Heron's formula

T=
S(s-a)(s-b)(s-c)

T=75(75-45)(75-35)(75-70)

T=
450000= 670.82
