Answer:
cosθ = 
Step-by-step explanation:
tanθ = -(65/72)
If it is in the 2nd quadrant, this means that y is positive but x is negative
tanθ= opposite/adjacent or (y/x)
tanθ=
We know that the adjacent value = -72 and the opposite value = 65
The hypotenuse can be get by the following
cosθ is just adjacent/hypotenuse
Our adjacent value is -72
Our hypotenuse is 97, therefore
cosθ =
Answer:
(y - 18) = -3/2 (x - 12)
Step-by-step explanation:
125% of 12 equals 15
75% of 18 equals 13 1/2
so the slope equals 4.5/-3 or -3/2
Answer:
D. 6
Step-by-step explanation:
| -6|
Absolute values means take the positive value
The positive value of -6 is +6
(-8)(-13) is 104, because it is multiplication. Hope this helps.
