The answer is in the attached file.
Answer:
21
Step-by-step explanation:
Answer:
(6, 9) (3, 0)
Step-by-step explanation:
Solve for each option using the slope formula:
Slope formula:
m = y2 - y1 / x2 - x1
m = 4 - 5 / 1 - 4
m = -1/-3
m = 1/3
This is not 3.
m = 0 - 9 / 3 - 6
m = -9 / -3
m = 3
This has a slope of 3!
m = 0 - 0 / -6 - 3
m = 0/ -9
m = 0
This is not 3.
m = 2 - 1 / 0 - 3
m = 1/-3
m = -1/3
This is not 3.
Given:
The value is
.
To find:
The values from the given options which are equal to the given value.
Solution:
We have,

It can be written as:

From the standard trigonometric table, we get






From the above values it is clear that the value of
and
are equal to
.
Therefore,
and
and equal to
. So, options B and C are correct.
