−4√41 / 41

−5√41 / 41

5√41 / 41

2.) What is the value of sinθ given that (−6, −8) is a point on the terminal side of θ?

−4/5

ONLY ANSWER IF YOU CAN EXPLAIN THIS TO ME CORRECTLY.

the expected value of the random variable : 0, 1 and 2

step-by-step explanation:

3x + 4y -25 =0 represents the amount of change sianna should recieve

statement #3: proof- ang is congruent to ang ecd : angles are congruent.  

step-by-step explanation:

1: the missing angles in statement #3  

a.) acb  

reason- the reason why the answer is acb is because angle ecd and angle acb are both the same size *that's what the word congruent means this is really simple.  

2: the missing word in reason #3  

c.) vertical  

reason- the reason why the answer is vertical is because the angles in that diagram on figure 2 is slanted, which is vertical, and the e and a both lay on vertical lines. along with the other's, but e and a are the 2 main points you want to focus on. and c is kind of like your starting point, because c is for both angles, not just one.  

i hope that was and understanding.
