Answer:
This needs more detail.
Step-by-step explanation:
Answer:
Using trigonometric ratio:
From the given statement:
and sin < 0
⇒ lies in the 3rd quadrant.
then;
Using trigonometry identities:
Substitute the given values we have;
Since, sin < 0
⇒
now, find :
Substitute the given values we have;
Therefore, the exact value of:
(a)
(b)
To find the x and y-intercept you plug in zero for the corresponding value that you are looking for. For example, if you are looking for x, plug 0 in for y.
To solve x-intercept: To solve y-intercept:
0=-2x-3 add 3 to other side y=-2(0)-3 substitute 0 for x
3= -2x divide 3 by -2 to isolate x y= 0-3
3/-2 = x (3/-2 , 0) is your x intercept y=-3 ( 0,3) is your y-intercept.
I hope this helps...
The answer is B, because a trapezoid is when the line and the dots are angled
