Answer:
Options (1), (2), (3) and (4)
Step-by-step explanation:
By applying the sine and cosine rules in the given triangle,
sinθ = 
cosθ = 
cos(30°) =
= 
= 
sin(30°) = 
= 
= 
cos(60°) = 
= 
= 
sin(60°) = =
= 
= 
Options (1), (2), (3) and (4) are the correct options.

Step-by-step explanation:
i+h=90
i+3h=210
so 2h=210-90=120
h=60
and i=90-60=30
so initial amount is $30 and hourly rate is $60
Using the combination formula, it is found that if the first flag is orange then the number of different signals consisting of 4 flags is 364.
The order in which the flags are chosen is not important, hence, the <em>combination formula</em> is used to solve this question.
<h3>What is the combination formula?</h3>
is the number of different combinations of x objects from a set of n elements, given by:

In this problem, considering that the first flag is orange, 3 flags will be chosen from a set of the remaining 14, hence the number of signals is given by:
