f/2 + 6
Answer:
9
Step-by-step explanation:
<span><span>Well, since we know that sin(x) = cos(90-x), we can transform the given into
2x - 8/3 = 90 - (4x - 10/3)
2x - 8/3 = 90 - 4x + 10/3
Now clear fractions by multiplying by three...
6x - 8 = 270 - 12x + 10
6x - 8 = 280 - 12x
18x = 288
x = 16
4x - 10/3 = 4(16) - 10/3 = 64 - 3.33 = 60.67 degrees.
Choice C.</span><span>

Maybe something like this:
1.69 = 169 / 100
√ 1.69 = √ ( 169 /100 ) = √169 / √ 100 = 13 / 10 = 1.3
Thank you.
For this case we have that by definition of trigonometric relations of rectangular triangles, that the sine of an angle is given by the opposite leg to the angle on the hypotenuse of the triangle. So:

Where h is the hypotenuse.

We cleared h:

We rationalize:
