Find the length of side a

​

Answer 1

d. 8

Explanation:

by Pythagoras theorem:

(Hypo)² = (Perp)² + (Base)²

(Perp)²= (Hypo)² - (Base)²

= 10 × 10 - 6 × 6

= 100 -36

=(underroot) 64

= 8

Answer 2

Let the sides be a, b and c

Given:
b= 6cm
c= 10cm

To find: Side a

Solution:
By Pythagoras’ theorem:
a^2+b^2=c^2
a^2+6^2=10^2
a^2+36=100
a^2=100-36
a^2=64
a= root of 64
a=8cm
