Answer:
0.546 , -4.71
Step-by-step explanation:
Given:
An angle's initial ray points in the 3-o'clock direction and its terminal ray rotates counter -clock wise.
Here, Slope = tan\theta
If θ = 0.5
Then, Slope = tan(θ) = tan(0.5) = 0.546
If θ = 1.78
Then, Slope = tan(θ) = tan(1.78) = - 4.71
The expression (in terms of θ) that represents the varying slope of the terminal ray.
Slope = m = tanθ, where θ is the varying angle

Answer:
Using trigonometric ratio:


From the given statement:
and sin < 0
⇒
lies in the 3rd quadrant.
then;

Using trigonometry identities:
Substitute the given values we have;

Since, sin < 0
⇒
now, find
:

Substitute the given values we have;

Therefore, the exact value of:
(a)

(b)

1.BD=AC
AC^2=(9^2)+(6^2)-2(9)(6)COS115
AC^2=117-108COS115
AC=√71.358
AC=8.447//
