Are the triangles similar?

yes by the aa rule in the problem

I believe it's the first one, I need some brushing up on this subject but I'm pretty sure it's the side angle side. This triangle is just smaller.

Step-by-step explanation:

<3

step-by-step explanation:

to determine whether a given function is even, we simply substitute x with -x in the expression. if the result after simplification is identical to the original equation, then the function is said to be even other wise odd.

f(-x) = (-x)^2 - (-x) + 8

      = x^2 + x +8

the resulting function is not identical to the original one;

f(-x) ≠ f(x)

therefore, f(x) is not an even function

i think da answer is

d.square root of 3
