VikaD [51]

The altitude of a shape or a polygon can be determined by drawing a perpendicular line from the base to the top most part of the polygon. In this case, the altitude is the segment BC where the ends are on the topmost of the cylinder and the base of the cylinder.

Vesna [10]
C^2= a^2 + b^2                  a=b
34^2= a^2 + a^2
1156=2a^2
a^2=1156/2
a^2=578
a=24.04

The side length is 24.04
            Or I got this also
Using the special triangle theorem , an isosceles triangle has a diagonal equal to the square root of 2 of the legs of the triangle. In this case, the length of the legs is 34/ sqrt of 2 or equal to 24.04 units . This rule is based on the Pythagorean theorem
If the length of each side = x.

By Pythagoras' Theorem:

x² + x² = 34²

2x² = 34²

x² = 34² / 2

x² = 578

x = √578
