Question

the sides of a triangle are 20, 21,29 . find the sum of altidues

Answer 1

Answer:

Step-by-step explanation:

The triangle with side lengths 20, 21 and 29 is right angled triangle 

so two altitudes of triangle are two side lengths of triangle 

they are 20,21

area of triangle = 1/2 base*altitudes 

                        = 1/2(20*21)

                          = 210cm²

now take 29 as base and altitude be h

210 =1/2(29*h)

420/29=h

sum of the altitudes = 20+21+420/29

sum of the altitudes = 1069/29 (or)55.482
