Perpendicular 70824

One perpendicular to the ABC right triangle has a length a = 14 cm, and a radius of the circle inscribed in this triangle r = 5 cm. Find the size of the diaphragm and its second perpendicular.

Correct answer:

c =  26.5 cm
b =  22.5 cm

Step-by-step explanation:

a=14 cm r=5 cm b=a2 r2 r (ar)=142 52 5 (145)=245=22.5 cm  c=a2+b2=142+22.52=253 cm=26.5 cm
 Verifying Solution:  s=(a+b+c)/2=(14+245+253)/2=263=31.5 cm S=a b/2=14 245/2=2315=157.5 cm2 r2=S/s=2315/263=2315:263=2315 632=2 63315 2=126630=5 cm b=245 cm=245 cm=22.5 cm
