Answer:
-1/5
Step-by-step explanation:
Perpendicular line is the negative inverse of the straight line.
So 5=-1/5
Answer: a
Step-by-step explanation:d
Answer:
A
Step-by-step explanation:
The opposite of a number is simply the number multiplied by -1 so the opposite of n is -n. "Between -3 and 0" tells us that the inequality is -3 < -n < 0.
the value of sin ∅ is 12/ 13
<h3>Quadrants and the "cast" Rule:</h3>
- In the first quadrant, the values for sin, cos, and tan are positive.
- In the second quadrant, the values for sin are positive only.
- In the third quadrant, the values for tan are positive only.
- In the fourth quadrant, the values for cos are positive only.
From the given question,
We have, cos ∅= 5/13
From the trigonometric identities, we have that
Then , let's substitute the value of cos ∅
Let make sin the subject of formula and find the squares of the fraction
sin²∅ =
Find the LCM
sin²∅ =
Find the difference
sin²∅ =
Find the square root
sin∅ =
sin∅ =
In quadrant II , sin is positive, so we have
sin ∅ = 12/ 13
Thus, the value of sin ∅ is 12/ 13
