Answer 2

Given:

A figure of an isosceles triangle.

The length of two equal sides = 37cm.

The perpendicular length = 12cm.

To Find:

The value of x.

Solution:

Let the triangle be named ΔABC,

Where, AB = AC = 37cm and AD = 12cm.

Here, ∠ADB = 90°.

Therefore, by the Pythagoras theorem,

In ΔADB,

H² = P² + B².

AB² = AD² + BD².

Putting the values,

37² = 12² + BD².

1369 = 144 + BD².

BD² = 1369 - 144.

BD² = 1225.

BD = √1225.

BD = 35cm.

Since, ΔADB = ΔADC.

So, BD = CD = 35cm.

Therefore, BC = BD + CD.

BC = 35 + 35.

BC = 70cm.

Hence, the value of x is 70cm.
