Answer:

Step-by-step explanation:
In any triangle, the sine of an angle is equal to its opposite side divided by the hypotenuse, or longest side, of the triangle (o/h).
Therefore, we have:

Answer:
Step-by-step explanation:
Since we have given that
Quadrant with radius 16 inches and angle 90° .
Since there are two quadrants:
So, Perimeter of quadrants is given by
Perimeter of this figure is given by
Hence, Second Option is correct.
3x4=12 12x5=60 60x6=360 360x7=2,530 2,530x9=22,690
4x+6y=8
3x+y=9
y = 9 - 3x
4x + 6( 9-3x ) = 8
4x + 54 - 18x = 8
14x = 46
x = 23/7
y = 9 - 3(23/7)
y = 9 - 69/7
y = - 6/7
