Calculate 81757

Calculate the size of the largest angle in triangle ABC if a = 7 cm, b = 8 cm, and c = 13 cm. Calculate the area of the triangle, the height per side a.

Correct answer:

S =  24.2487 cm2
v =  6.9282 cm

Step-by-step explanation:

a=7 cm b=8 cm c=13 cm  s=(a+b+c)/2=(7+8+13)/2=14 cm  S=s (sa) (sb) (sc)=14 (147) (148) (1413)=14 3=24.2487 cm2
S = 2a v  v=2 S/a=2 24.2487/7=4 3=6.9282 cm
