Question

someone help me out. i could use it please. O is inscribed in ABC , which has a perimeter of 76 cal. What is the length of CE?

Answer 1

C.E=18 cm

Explanation:

we know that

If the circle O is inscribed in triangle ABC

then

A.F=A.D=6 cm

B.D=B.E=14 cm

C.F=C.E=?

The perimeter of triangle is equal to

P=2(6)+2(14)+2(C.E)

P=76 cm

so

76=2(6)+2(14)+2(C.E) -----> solve for C.E

76=12+28+2C.E

2C.E=76-40

C.E=36/2

C.E=18 cm
