Question

the length of two sides of a triangle are equal. the square of the hypotenuse is 800 cm2 . find the length of each side​

Answer 1

Answer:

Step-by-step explanation:

Let the equal sides be x

Therefore ,

800 sq = x sq + x sq

640000=2x sq

320000=xsq

x=400 root 2

Answer 2

Answer: See image below carefully

AB = BC = X

AB∧2 + BC∧2 = AC∧2

X∧2 + X∧2 = (800cm∧2)

2X∧2 = 800 cm∧2

X∧2 = 800/2 (cm∧2)

X∧2 = 400cm∧2 = (20cm)∧2

       = 20cm

NOTE:- ((∧) means square)
