Answer 1

Answer:

$x=\sqrt{13}$

Step-by-step explanation:

Base of the isosceles triangle = 4

Perpendicular of the triangle = 3

In an isosceles triangle , a perpendicular bisects a base equally. So, here the isosceles triangle consist of 2 right angled triangles.

In that right angled triangles,

Base = 4/2 = 2 (∵ A perpendicular divides a base into 2 equal parts. )

Perpendicular = 3

Hypotenuse = x

So , according to Pythagorean Theorem ,

$Hypotenuse = \sqrt{Base^2 + Perpendicular^2}$

Using all the values above into the formula gives :-

$x =\sqrt{2^2 + 3^2} = \sqrt{4+9} =\sqrt{13}$
