You are given values for the adjacent side of <x and the hypotenuse of a right triangle. This defines the Cosine of an angle
Equation
Cos(x) = a/c the way you have labeled it.
Givens
a = 9
c = 18
Solution
Cos(x) = a / c
Cos(x) = 9 / 18
cos(x) = 1/2
x = cos-1(1/2)
x = 60 degrees
Answer
x = 60
Answer:
2
Step-by-step explanation:
from (0,1) to (1,3)
is up 2 over 1
2/1=2
hope this helps!
Let x be the angle, the complement is 90-x. the sup is 180-x.
So 180-x = 3(90-x)+12
180-x=282-3x
180+2x=282
x=102
x=51
Answer:
So the mean of 263,240,256 is 253 and the mean of 12,13,17 is 14
Step-by-step explanation:
To get the mean of these numbers you add all three of them together then you divide them by the amount of numbers so you are going to add 263+240+256=759 then you divide by 3
