Answer 1

Before we solve:

• Given that - The length of the unequal side of an isosceles triangle is 6 cm. And the three sides are in the ratio 3:4:4.
• Need to find - Length of the equal sides of the isosceles triangle.

Solution:

We know that the measure of any two sides of an isosceles triangle is equal.

So, let the sides be 3x, 4x and 4x.

The unequal side will be 3x.

According to the question,

$\sf \implies \: 3x = 6cm$

$\sf \implies \: x = \frac{6}{3}$

$\sf \implies \: x = 2$

So, other sides of the given isosceles triangle are:

4×2 = 8 cm

Therefore, equal sides of this isosceles triangle are of measure 8 cm.
