Answer:
C
Step-by-step explanation:
Sin(28) is approximately 0.4695
After rewriting all of the options as a decimal:
a) 0.8823
b) 1.875
c) 0.4706
d) 0.5333
when rounding the sin(28) to the nearest hundredth... you get 0.47
Therefore, sin(28) is c) 
Answer:
x = 20
Step-by-step explanation:
Assuming you require the value of x
The exterior angle of a triangle is equal to the sum of the 2 opposite interior angles.
7x - 15 is an exterior angle of the triangle, thus
7x - 15 = x + 28 + 4x - 3 , that is
7x - 15 = 5x + 25 ( subtract 5x from both sides )
2x - 15 = 25 ( add 15 to both sides )
2x = 40 ( divide both sides by 2 )
x = 20
Answer:
46.66% chance of red marble
Step-by-step explanation:
Red Marbles / Total Marbles gives you the percent
14 / 30 = 46.66%
Opposite side = sqrt (3^2 - 2^2 ) = sqrt5
sin theta = -sqrt 5 / 3 as the sine is negative in the 3rd quadrant
csc theta = - 3 / sqrt5
