Find the value of cos(θ) for angle θ in standard position with a terminal brain that passes through the point (4,-3)
2 answers:
Answer:
D
Step-by-step explanation:
(4,-3) lies in the fourth quadrant where cos is positive
cos(θ) = adjacent/hypotenuse
hypotenuse² = 4² + 3² = 25
Hypotenuse = 5
cos(θ) = 4/5
Answer:
-3/4
Step-by-step explanation:
cos theta = (adjacent /hypothesis) =(-3/4)

Step-by-step explanation:
5x + 8 - 3x = 10
First you can combine the like terms.
5x - 3x + 8 = 10
2x + 8 = 10
- 8 - 8
2x = 2
x=1
