Answer:
The cosine of the angle is <u>positive</u>
The sine of the angle is <u>negative</u>
Step-by-step explanation:
We are given that
angle lies in fourth quadrant
and we know that
In first quadrant:
sin is positive
cos is positive
In second quadrant:
sin is positive
cos is negative
In third quadrant:
sin is negative
cos is negative
in fourth quadrant , cosine of angle is always positive
and sine of angle is always negative
so,
The cosine of the angle is <u>positive</u>
The sine of the angle is <u>negative</u>
Slope of a Line Passing through two points (x₁ , y₁) and (x₂ , y₂) is given by :
Given Points are (-3 , 5) and (6 , -1)
here x₁ = -3 and x₂ = 6 and y₁ = 5 and y₂ = -1
Option D is the Answer
The best definition for the term substitution would be...
the action of replacing someone or something with another person or thing.
1 and 5 are equal, 1 and 8 are equal, 5 and 8 are equal
So if 1+5=100 and they're equal divide by 2: 100/2=50. So if 1 and 5 equals 50, then 8 also =50 :)
If a right triangle is 90° , the other acute triangle would be 10° because 90 - 80 = 10
