Question

The lengths of the three sides of a triangle are given as 8 cm, 13 cm and 15 cm. The ratio of their corresponding altitudes to the opposite vertices will be:​

Answer 1

Answer:

Here a=5cm, b=12cm, c=13cm

=

=

Let A be the area of the given triangle, then

A =

=

= = 30 cm2

Let p be the length of the perpendicular from vertex D on the side BC, then

A =

2A = 13p

2 × 30 = 13P

Hence, length of perpendicular from the opposite vertex to the side whose length is 13 cm is cm.

Answer 2

Answer:

Given

FORMULA OF TRAINGLE

sum of lenght of all three sides

=8+13+15

=36

= the altiudes of traingle will be 36
