Hi , the answer is 15 miles per hour because 45 divided by 3 equals 15 , one hour equals to 15 , two hours =30 and three hours =45 , it goes by 15.
calculate length of the sides of the rectangle and multiply then do the same with the parallelogram
Total area is 51 square units
Answer:
X = 48
Step-by-step explanation:
When you type sin(42) in your calculator it will give you something around 0.669.
If you try reverse sinus sin-1(0.669) it will give you 42.
Therefore you can say that:
Cos(x) = 0.669
So you can reverse the cos to get your answer
Cos-1(0.669) = 48
Or
Cos-1 (sin(42))
