Answer:
d
Step-by-step explanation:
Using the Cosine rule to find ∠ A
cosA = 
= 
= 
= 
, then
∠ A = 
( ) ≈ 84.9° ( to 1 dec. place )
Given:
The inequality is:
To find:
The solution of the given inequality.
Solution:
We have,
Multiply both sides by 3.
Divide both sides by -8 and change the sign of inequality.
It can be written as:
Therefore, the correct option is A.

Answer:
<h2>x = 12</h2><h2 /><h2>y = 4√3</h2>
Step-by-step explanation:
<u>To find x we use cosine</u>
cos∅ = adjacent / hypotenuse
x is the adjacent
8√3 is the hypotenuse
cos 30 = x / 8√3
x = 8√3 cos 30
<h3>x = 12</h3>
<u>To find y we use sine</u>
sin∅ = opposite / hypotenuse
y is the opposite
8√3 is the hypotenuse
sin 30 = y / 8√3
y = 8√3 sin 30
<h3>y = 4√3</h3>
Hope this helps you
