Answer:
x = 15
Step-by-step explanation:
Assuming 3x and x-60 are in degrees, you can use:
cos(a) = sin(a+90)
To rewrite the equation as:
sin(3x) = sin(x-60+90)
sin(3x) = sin(x+30)
3x = x+30
2x = 30
x = 15
But, solving 3x = x+30 which simplifies to x=15 is not the only solution to this equation, as you can see in below picture. Finding all solutions is a bit more work, but maybe that is not required in your case.
3 8/10 of a mile. You subtract 5.4 from 9.2 and get 3.8 and 3.8 in fraction form is 3 and 8/10. 3 8/10 simplyfied is 3 4/5
They are arranged in opposite directions Answer ( 2.4 - 1.8 = 0.6)
