Question

the perimeter of triangular field is 300cm and its sides are in ratio 5:12:13 find the length of the perpendicular from the opposite vertex to the side whose length is longest​

Answer 1

Answer:

Length of perpendicular line is 10.08 cm

Step-by-step explanation:

Let side of the triangle is X

Then they are in 5:12:13 ratio

Perimeter = 300 cm

5x+12x+13x= 300

30x=300

X= 300/30

X= 10

Sides are 50, 120 and 130 cm

Longest side is 130 cm

Now consider triangle with perpendicular bisector bisect the longest side form a right angles triangle with opposite side vortex

Base is half of the longest side= 65 cm

Using Pythagoras theorem

12^2 = 6.5^2+ y^2

Y^2= 144-42.25

Y^2= 101.75

Y= 10.08 cm

Length of perpendicular line is 10.08 cm

Answer 2

Answer:

Let the sides of the triangle be 3x, 4x and 5x

∴ The perimeter of the triangular field = 144 m

⇒ 3x + 4x + 5x = 144

⇒ 12x = 144
