Question

their feet is 12 m, find the distance between their tops.
5 In a right-angled triangle, if hypotenuse is 20 cm and the ratio of the other two sides is
43 find the sides.
6 If the sides of a triangle are in the ratio 3: 4: 5, prove that it is right angled
trian​

Answer 1

Step-by-step explanation:

Let the sides be 4x and 3x.

By Pythagoras theorem we have,

x²+y²=z²

(4x)²+(3x)²=20²

16x²+9x²=400

25x²=400

x²=16

x=√16

x=4 (Rejecting -4 as length cannot be negative.)

As we know that the sides are 4x and 3x,

Plugging in value of x we get the sides as,

16cm and 12cm.

Hope this helps.
