Answer: option 3 is the correct answer
Step-by-step explanation:
Let us look at the various trigonometric ratios
Sin Ф = opposite side/ hypotenuse
Cos Ф = adjacent side / hypotenuse
Tan Ф = opposite side / adjacent side
Therefore, tan Ф = sin Ф / cos Ф
This means that if cos Ф=-8/17 and sin Ф is negative, then the hypotenuse is negative
To determine the adjacent side, we will apply Pythagoras theorem
Hypotenuse ^2 = opposite ^2 + adjacent ^2
-17^2 = 8^2 + adjacent^2
adjacent^2 = 289 - 64 = 225
adjacent = √225 = 15
tan Ф = 8/15
Answer: y = x -1
reasoning: the slope is 1 because the rise/run = 1/1, which simplifies to 1.
the y intercept is -1 because the line passes through the y axis at -1.
hope this helps!
Answer:
houston
Step-by-step explanation:
They’re both like terms so you add them together normally
10+9=19
so
19j2
