Answer:
Option 4
Step-by-step explanation:
The square root of 25 is 5 so it is not number 1
The root of 400 is 20 so it is not number 2
the square root of 676 is 26 so it not that.
That leaves option four which is irrational
<span>x=theta
so we know that tanx = sinx/cosx
therefore is tanx = 4/3 and sinx = -4/5
we can set up an equation to find cosx
so 4/3 = (-4/5)/cosx
we can multiply x to have cosx(4/3)=-4/5
we can then divide 4/3 over so we have
cosx = (-4/5)/(4/3)
therefore, cos x = -3/5
</span>
there is the answer
i hope this help
5/8 + 1/4 = 7/8
Hope this helps you
