Answer:
1/3 = x
Step-by-step explanation:
y - y₁ = m(x - x₁)
y - (-2) = ¹/₂(x - 4)
y + 2 = ¹/₂(x) - ¹/₂(4)
y + 2 = ¹/₂x - 2
- 2 - 2
y = ¹/₂x - 4
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:
If you simplify the equation, you will get, 
Step-by-step explanation:
You have to combine like terms.
and 
are like terms, so you add them together.
