1:1.67. You divide both sides by 1.8 to reduce the smaller measurement to 1.
1.8/1.8 : 3/1.8 = 1:1.67 and there you go.
Cos(B) = adjacent / hypotenuse
Cos(B) = 11/27
Cos(B) = 0.4074
B = Cos-1(0.4074)
Put this into your calculator like this.

Answer:
We are given a inequality with the equality sign in terms of variable 'r' as:
Now we find the solution of the following inequality by solving for 'r'.
We subtract 3 from both side of the inequality to obtain:
Now we multiply both side by "-1" to obtain:
Now on dividing both side of the inequality by 2 we obtain:
Hence, the solution of the inequality are the set of all the points on the number line which are less than equal to -8.
i.e. the shaded region is to the left of -8 and closed circle at -8.
i.e. the solution is: (-∞,-8].
Number 2 graph is the correct graph of the solution.
