L = -4,4
E = -2, -3
N = 2,1
I = 4,3
E = 1,3
By using trigonometric relations, we will find that:
sin(θ) = (√33)/7 = √(33/49)
<h3>How to find the value of the sine?</h3>
Remember that for a right triangle, we have the relations:
cos(a) = (adjacent cathetus)/(hypotenuse)
sin(a) = (opposite cathetus)/(hypotenuse).
Here we know that:
cos(θ) = 4/7
Then we can say that we have a triangle with an adjacent cathetus of 4 units and a hypotenuse of 7 units. Now we need to find the other cathetus.
opposite cathetus = √(7^2 - 4^2) = √33
Then we can write:
sin(θ) = (√33)/7 = √(33/49)

I need help on that do you know the answer
Answer:
You have 5 27/28
Step-by-step explanation:
- 6 20/28 - 21/28= 5 27/28
- 5 27/28
Check the picture below, that's the "inscribed angle theorem"
