Answer:
Cot(theta) = - 0.75 or -3/4
Step-by-step explanation:
The hypotenuse is 5
The y value is 4
We need to find the corresponding x value.
x^2 + y^2 = z^2
X = ?
y = 4
z = 5
x^2 + 4^2 = 5^2
x^2 + 16 = 25
x^2 = 9
Now in this case, you are in quadrant 2, so the x value is - 3
sqrt(x^2) = sqrt(9)
x = - 3
The cot value is the adjacent (x value) / the opposite ( y ) value
Cot(theta) = -3/4
cot(theta) = -0.75
Solve for y
minus 10x from both sides
5y<-10x+15
divide both sides by 5
y<-2x+3
Answer:
What grade are you?
Step-by-step explanation:
Cause it's hard even gòogle can't answer it.
1. you may want to find the area of the floor of a house to maybe buy tile or hardwood flooring and you need to know the area of the floor to know how much material is needed
to find the area you must multiply hight x the width
2. 4 x 6 = 24
3. 6 x 3 = 18
4. 3 x 4 = 12
