By definition we have to:
Sin (x) = C.O / h
Where,
x = angle
C.O = opposite leg
h: hypotenuse.
Substituting values we have:
Sin (C) = AB / 82
We should look for AB. For this, we use the following relationship:
AB ^ 2 + 80 ^ 2 = 82 ^ 2
Clearing AB:
AB = root ((82 ^ 2) - (80 ^ 2))
AB = 18
Substituting we have:
Sin (C) = 18/82
Simplifying:
Sin (C) = 9/41
Answer:
the trigonometric ratio for sin C is:
Sin (C) = 9/41

Step-by-step explanation:
<u>Angles in a Triangle</u>
There are two basic relations of angles we need to recall:
- Supplementary angles add up to 180°
- Internal angles of a triangle add up to 180°
Note a, b, and c are the internal angles of the triangle. The angle c is what is needed to a+b to complete 180°, thus:
c = 180 - ( a + b )
Also, note c and d are supplementary angles. Again, c is what is needed to d to complete 180°, thus
c = 180 - d
From the two relations above, it follows that:
a + b = d
Answer:
y=-1/2x-3
Step-by-step explanation:
Answer:
x=2,y=2
Step-by-step explanation:
This question is a simultaneous equation
So let's solve
3x+y=8...(1)
2x+2y=8....(2)
Multiply (1) by 2
6x+2y=16...(3)
Substrate (2) From (3)
4x=8
Let's make x the subject of formula by dividing both sides by 4
x=2
So let's substitute the value of x into (1)
3x+y=8
3(2)+y=8
6+y=8
y=8-6
y=2
Therefore x is 2,y is 2
