Answer:
13) B
14) A
Step-by-step explanation:
13) Knowing that the interior angles of a triangle add up to 180, we can see that angle A is 53°. To find length c, we can use either sine or cosine. Let's use sine:
sin 37° = b/c = 15.9/c ---> c = 15.9/sin 37 = 26.4
To solve for side a, use cosine:
cos 37° = a/26.4 ---> a = 26.4cos37 = 21.1
14) Again, knowing that the interior angles of a triangle add up to 180, we know that angle B is 52°. This time,let's use cosine (although you may choose sine if you want):
cos 38° = b/16 ---> b = 16cos38 = 12.6
To find side a, use sine:
sin 38° = a/16 ---> a = 16sin38 = 9.9
Answer:
0.500
Step-by-step explanation:
Okay, we know the price of the child's ticket (x), which is 5.75 dollars less than the adult's ticket.
Let's say that the price of the adult's ticket is a. Since the child's ticket is 5.75 less that the adult's ticket, we can write it this way:
a = 5.75 + x
