Answer:
x=8
Step-by-step explanation:
p=(l+b)
140=2(x+4x-2)
140=2(9x-2)
140=18x-4
140+4=18x
144=18x
144/18=x
8=x
To find the answer to this problem, you can use the unit circle to see that pi over 6 radians is equal to 30°
Another way is to use the equation: degrees = radians • (180 over pi)
In this example, plugging in the radians portion of the equation gives us: degrees = (pi over 6) • (180 over pi), which will become degrees = (180pi over 6pi)
Simplify and pi cancels out to give us degrees = 30
Answer: 30°
Answer:
y+1=8/9(x+4)
Step-by-step explanation:
Tell me if you want one!
Division property of equality, because you have to divide 8x and 80 by 10
Y=ax+b
a... slope
b... interception on the line y
you get the equation y=-1/2 *x + 12
