In a right angle the hypotenuse is Xcm Adjacent is y cm while the opposite is Z cm , the length of the hypotenuse is X cm , is given by the formula X=√x^2+y^2 a) Find the value of x when y = 2 1/2 and z = 6cm
b) Find the value of y when X = 16 and X^2 = 60

It appears that there may be a typo in the original question, as if:

of a right triangle, then using Pythagoras' Theorem:

a) Given:

And using :

b) Given:

And using   :

see below

step-by-step explanation:

x+2> 6

subtract 2 from each side

x+2-2 > 6-2

x > 4

there is an open circle at 4 since is it is greater than and the line goes to the right
