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

No it’s makes more than it so no
Answer:
x equal 104
Step-by-step explanation:
since 8 needs to go into something 13 times we can multiply
8 x 13 to get
104
104 divided by 8
equals 13
This is a bad question. It should really be asking about the solutions of f(x)=0 (an actual equation) or the <em>zeros </em>of f(x).
The zeros of a function f(x) are the xs where f(x)=0. That means where the curve intersects the x axis. That's (-4,0) and (2,0) on the graph.
Answer: C (-4,0), (2,0)
