In triangle def , df = 16 and angle f = 45. find the length of a leg. leave your answer is radical form. a. 8 square root of 2 *my answer* b. 128 c. 16 d. 16 square root of 2 can someone double check me? and if i’m wrong, can you explain how to do this ?

option a.

step-by-step explanation:

if you look closely at the graph, we can notice that the function is not defined at two different points.

if you look at functions b and c, you will notice that both functions are not defined at just one point. the function b is not defined at x= -5/2 and function c is not defined at x=-5. both options are discarded, given that our function should not be defined at two fiferent points.

now, if you look closely at the graph you will notice that the function sketched is not defined at x=5 and x=-2.
