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.
Answer:
13
Step-by-step explanation:
All you do is divide 39 by 3 and that gets 13
It would mean the fence has to be 41 feet long and 36 feet wide. To find the perimeter of the fence, it would be 41+41+36+36 which equals 82+72 so 154 feet of fencing
Y= mx+b is the the equation just plug it in
Slope is M and y-intercept is B
So 11) is Y= -1x+2
