Using trigonometric relations, we will see that:
sin(θ ) = -0.8
<h3>
How to get the sine of the angle?</h3>
For any point (x, y), the angle between the positive x-axis and the ray that connects the origin with the point (x, y) is:
θ = Atan(y/x)
In this case, the point is (3, -4), then the angle is:
θ = Atan(-4/3) = -53.13°
Then the sine of theta is:
sin(θ = -53.13°) = -0.8

Answer:
x=4
Step-by-step explanation:
The question shows an isoceles triangle, which means both sides should equal:
28=9x-8
36=9x
x=4
Answer: 36/100
Step-by-step explanation:
1/3 x 1/6 / 1/2=36/100
I don't know? well i know but i'm not sure pretty sure it is
