It is -3 to start off with, on Monday. On Tuesday morning it would be -3 - 2 degrees, = -5 degrees. By Tuesday evening it was 4 degrees lower than in the morning, so -5 - 4 degrees = -9 degrees on Tuesday evening.
Hope this helps xox :)
A
Working:
Tan(angle)=opposite/adjacent
Tan60 = x/7root3
x=7root3 x Tan60
Enter in calculator
x=21
In your equation: a+(-4)=-13
you then add four to each side,
so a= negative 13 plus 4
so a= -9
Answer:
The distance between them is 230.65 miles
Step-by-step explanation:
Here we use the Cosine formula

Now the distance for one hour is
= 230.65 ÷ 1
= 230.65 miles
