Supplementary angles sum up to 180°, suppose the supplement of 161° is x. Then
161+x=180
solving for x we subtract 161 from both sides
161-161+x=180-161
x=19
thus the supplement is 19°
5 red, 3 blue, 7 white.....total of 15
probability of 1st drawn being red : 5/15 reduces to 1/3
without replacement
probability of 2nd being red : 4/14 reduces to 2/7
probability of both : 1/3 * 2/7 = 2/21 <==
To get 51/60 courted to decimal you simply divided 51 by 60
We have that Options That are correct are given as
From the question we are told
Which of the following is true for this image?
a. CD is the perpendicular bisector of AB
b. Neither line segment is a perpendicular bisector.
c. AB is the perpendicular bisector of CD
d. both line segments are perpendicular bisectors.
Generally
- CD is the perpendicular bisector of AB
This is True Because CD Cuts Across AB at angle 90 in the middle
- Neither line segment is a perpendicular bisector.
This is Untrue Because CD Cuts Across AB at angle 90 in the middle
- AB is the perpendicular bisector of CD
This is True Because AB Cuts Across CD at angle 90 in the middle
- Both line segments are perpendicular bisectors.
This is True
