Answer:
Step-by-step explanation:
I'm going to use a Pythagorean identity to help make this make sense.

We are given that cos(0) = 1, so
cos²θ = 1² which simplifies to
cos²θ = 1. So filling into our trig identity:
sin²θ + 1 = 1 and
sin²θ = 0 then
sinθ = √0 so
sinθ = 0
so
sin(0) = 0
Answer:
x= -10
Step-by-step explanation:
4.5(8 - x) + 36 = 102 - 2.5(3x + 24)
4.5(8) - 4.5(x) + 36 = 102 - 2.5(3x) -2.5(24)
36 - 4.5x + 36 = 102 - 7.5x - 60
72 - 4.5x = 102 - 7.5x - 60
-4.5x = 102 - 7.5x - 60 - 72
-4.5x + 7.5x = -30
3x = -30
x = -30/3
x = -10
Sorry if its wrong, I try my best.
Answer:
Slope = -1/4
Step-by-step explanation:
Slope = (-8 + 5)/(0 + 12) = -3/12 = -1/4
