If Sin 3x= Cos (x-60), find the value of x
1 answer:
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:
m = -2/7
Step-by-step explanation:
We can find the slope when given two points by using
m = (y2-y1)/(x2-x1)
=(4-2)/(-5-2)
=2/-7
= -2/7
2748?? Your question is a little unclear Happy studying ^_^
The name of place value of 9 in 199 is ones.
The second 9 has a value of tens.
The number 1 has a place value of hundreds.
3 - 5m plug in 350 for m 3 - 5(350) multiply 3 - 1,750 subtract -1,747
D should be the correct answer
