The three main trig functions are sine (written as sin), cosine (written as cos), and tangent (written as tan).
Sine of an angle = the length of the side opposite (aka across) the angle / the length of the hypotenuse
Cosine of an angle = the length of the side adjacent (aka the side next to which isn't the hypotenuse) to the angle / the length of the hypotenuse
Tangent of an angle = the length of the side opposite of the angle / the length of the side adjacent to the angle.
The acronym to remember this is SOHCAHTOA
SOH | CAH | TOA
SOH means sin(x) = opposite/hypotenuse
CAH means cos(x) = adjacent/hypotenuse
TOA means tan(x)= opposite/adjacent
cosB = length of adjacent side/length of hypotenuse = 7/25
tanB = length of opposite/length of adjacent = 24/7
sinB = length of opposite/length of hypotenuse = 24/25
Answer:
The value is 
Step-by-step explanation:
From the question we are told that
The population mean is 
The proportion is 
The value considered is 
Generally given that the speed measurement is normally distributed we have that
Generally
Hence
Answer:
x = 30
Step-by-step explanation:
m<E = [m(arc)AD - m(arc)BC]/2
50 = (130 - x)/2
100 = 130 - x
-x = -30
x = 30
D. 7
a constant is a term without any variables
The value of the variable would be 82, as the inside angles of a triangle add up to 180
