Answers:
- pi/3 radians = 60 degrees
- pi/4 radians = 45 degrees
- pi/2 radians = 90 degrees
=======================================
Explanation:
To apply the conversion, we use the idea that pi radians is equivalent to 180 degrees
pi radians = 180 degrees
To convert from radians to degrees, we'll multiply by the conversion factor (180/pi)
This leads us to the following:
- (pi/3 radians)*(180/pi) = (pi*180)/(3*pi) = 180/3 = 60. So pi/3 radians converts to 60 degrees
- (pi/4 radians)*(180/pi) = (pi*180)/(4*pi) = 180/4 = 45. So pi/4 radians converts to 45 degrees
- (pi/2 radians)*(180/pi) = (pi*180)/(2*pi) = 180/2 = 90. So pi/2 radians converts to 90 degrees
Answer: x = 3
Step-by-step explanation:
When the base is the same, the exponents are the same:
3-2x = -x
solve fore x
add 2x to both sides
3-2x = -x
+2x +2x
x = 3
Answer:
Step-by-step explanation:
Graph of x=5 is vertical straight line parallel to y-axis and perpendicular to x-axis. The points on graph have the x-coordinate as 5 and y-coordinate varies.
Similarly, line parallel to x=5 or y-axis passing through point (-6,6), in that all the points have same x-coordinate as -6. So the equation of line will be x=-6
For simplicity of visualization graph of both the equation x=5 and x=-6 are attached.
