The measures of two angles in a triangle are shown in the diagram. Which equation can be used to find the value of x? 67° 67

40 i don’t know lololol

why are you giving so many marks make your marks less and make a question list so that i can understand your question very nicely

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
