A perpendicular bisector forms two right angles and splits the line in two equal parts.
The altitude does create two right angles, but doesn't have to create two equal parts.
Answer:
Step-by-step explanation:
you would show x and y lines and title frequency to side and colours to bottom
0-40 on the y axis title is frequency
and on bottom graph put the colours. red blue and green always using equal intervals for names or time or colours along the x axis.
Answer:
here we have -C
The Coefficient of -C is -1
Okay, so let the 2nd angle be just x. Then the first angle is 2x, since it is twice the measure of the second angle (2 times x), and the 3rd angle is 96 + x, since it is 96 MORE (addition) than the 2nd angle. So our 3 angles are: Angle 1: 2xAngle 2: xAngle 3: 96 + x We know that all 3 angles in a triangle add up to be 180. So we can add these 3 angles together and set it equal to 180. 2x + x + (96 + x) = 1803x + 96 + x = 1804x + 96 = 1804x = 84x = 21 Now we can plug x = 21 back into our 3 angles from earlier getting: Angle 1: 2(21) = 42Angle 2: 21Angle 3: 96 + 21 = 117 If you add all 3 of these up, you'll see that they equal 180.
To check whether the two lines are parallel or not, without using graphing, first we write them in slope intercept form , which is
Now we compare the slopes of both lines and if the slopes are equal, then the lines are parallel .
So without graphing, we can also check whether the given lines are parallel or not .
