Answer:

Step-by-step explanation:
think of this triangle being made up of 2 triangles with the lengths of 5, 4, and x.
x being the hypotenuse, 5 being one of the legs, and 4 being one of the legs. (8/2).
pythagorean theorem:
a^2 + b^2 = c^2
5^2 + 4^2 = x^2
25 + 16 = x^2
41 = x^2
x = sqrt 41
0.95 is rational number
answer is option 2
a rational number<span> is any </span>number<span> that can be expressed as the quotient or fraction
</span>
so 0.95 = 95/100
hope that helps
