Question

if the unequal side of an isosceles triangle is 6cm long

Answer 1

Given,
Unequal side = 6 cm.
Ratio of sides = 3:4:4.

Let the common ratio be x.

Then the ratio is 3x:4x:4x.

It is given that 3x = 6.

So, x = 6/3.
x = 2.

Now that we have found out the value of the common ratio we can find the equal sides by replacing the common ratio with its value.

So, 4x = 4(2) = 8.

Therefore, the measure of the length of the equal sides is 8 cm.

Answer 2

Answer is 9 cmHope it helps.Thanx.
