Answer:
sin θ = 4/5
Step-by-step explanation:
The Pythagorean theorem tells you the distance (h) from the origin to the terminal point:
h² = (-3)² +(4)² = 25
h = 5 . . . . . . . . take the square root
The mnemonic SOH CAH TOA reminds you ...
Sin = Opposite/Hypotenuse
For angles other than 1st-quadrant angles, it can sometimes be difficult to identify the relevant sides of the relevant triangle. If the angle were a 1st-quadrant angle, it would be clear that the side opposite the angle is the y-coordinate of the point on the terminal side. That remains the case for all angles. The hypotenuse is always the positive distance from the origin to the terminal point.
So, you have
sin θ = opposite/hypotenuse = 4/5
Hey there :)
Let us translate each one separately
{ Using w for unknown }
The
difference of a number divided by 3 and 5
is 2
'is' is the key-word, meaning you apply the = sign
Difference is subtraction
→ a number divided by 3 - 5 = 2
This is your equation: →
Solving for wTake 5 to the other side
[ When you see subtraction you do addition on the opposite side ]
→
![\frac{w}{3}=7](https://tex.z-dn.net/?f=%20%5Cfrac%7Bw%7D%7B3%7D%3D7%20)
Take 3 to the other side
[ When you see division you do multiplication on the opposite side ]
w = 3 x 7
w = 21
