Answer:
x= 45
Step-by-step explanation:
x= -15*-3
x= 45
cos(3x) = cos(2x+x)
= cos(2x) cos (x) -sin(2x)sin(x)








23.75 miles, because you would take 4 and 3/4 (4.75) and multiply by 5 :)
The first number is 27 and the second number is 45 so the ratio would be 27;45
Answer:
B= -40
Step-by-step explanation:
So a right triangle has to = 180
So we write the given, which 124+99
we are trying to get 180 so lets subtract that by the equation, 180-124+99
180-(124+99)
12+99=223
180-223
=-43
But in your case it has to be rounded to the nearest tenth
So the answer is -40
