Find the supplement of each of the following angles:

(i) 42

(ii) 90

(iii) 124

(iv) 3/5 of a right angle

Answer:

(i) We know that the supplement of 42 can be written as

42 = 180 - 42 = 138

(ii) We know that the supplement of 90 can be written as

90 = 180 - 90 = 90

(iii) We know that the supplement of 124 can be written as

124 = 180 - 124 = 56

(v) We know that 3/5 of a right angle can be written as 3/5 × 90 = 54

54 = 180 - 54 = 126

"hello students welcome to linux q and a
video session
i'm saf your math tutor and question for
today is
find the supplement of each of the
following angles
now here the angles are given the first
one is 42
okay so first one here we'll find the
first one
supplement of 42
so the first one
yeah four angles are given the first one
is
supplement of 42
here we'll do second
third and fourth
fine continuing here with 42
have to find the supplement now we know
that supplement can be written as 180
minus 42
so supplement of
any angle
is 180
minus angle that
angle okay so here as per this we can
write
supplement
of 42 is
180 minus 42
so it is 180 minus 42
is equal to 138
this is the supplement of 42. the second
one is
90.
so supplement we have to find the
supplement of 90 degree
here also degree
supplement of 90 degree can be written
as 180 minus 90
so here 180
minus 90 degree
will be equal to 90 degree
hence
supplement
of 90 degree
is 90
the third one is 124 degree
so here 124 degree
solving this you know that the
supplement
of
124 degree is 180 minus 124
and that is 180 minus 124
will be equal to
56 degree
right so here we have
supplement of
124 degree is
56 degrees
fine the fourth one the fourth one is
three by five of a right angle
three by five of
a right angle
so this is the question for us now
three by five of a right angle three by
five
off means it is a keyword its sign is
multiply
so three by five of right angle right
angle is 90 degree
will be equal to
how to see t by pi of 90 degree
will be equal to 54 you can simplify it
and you will get 54 so 54
here now we have to find
three by five of right angle its
supplement
now the supplement of 54 we have to find
we already know that supplement of 54 is
180 minus 54.
hence 180 minus 54
is equal to 126 so these are the
one answers for each of the
supplements asked the answers are
138 degree for 42 degree 90 degree for
90 degree 156 degree for 124 degree
and three by five of our right angle
supplement is
126 degree that is our answer
