Answer:

Step-by-step explanation:
The given trigonometric equation is

We take the inverse cosine of both sides to obtain;


Group similar terms t obtain;


64; Line pq is correspondent with line ab and triangle PQR is 4 time as big as triangle ABC.
-7x+14>-3x-6
Add 3x to both sides
-7x+14+3x>-3x-6+3x
-4x+14>-6
Subtract 14 from both sides
-4x+14-14>-6-14
-4x>-20
Divide both sides by -4
-4x/4>-20/-4
x<5
