Answer:
The value of x is 64
Step-by-step explanation:
Given:
Length of the Legs of the triangle = 6 and √x
Hypothenus = 10
Required
Find x?
The legs of a rectangle is what is regarded to as the adjacent and the opposite sides of the triangle.
Assuming the following
Adjacent = 6 and Opposite = √x
We can then solve the given example using Pythagoras theorem as foloes;
By substituting 10 for Hyp; 6 for Adj and √x for Opp
Simplify
