Match the following columns:
The correct answer is:
A. – …….., B. – ……….,
C. – ………, D. – ……….,
Answer :
(a) – (r), (b) – (s), (c) – (p), (d) – (q)
(a) – (r)
X + y = 90
X + 2x/3 = 90
5x/3 = 90
X = 270/5
= 54
(b) – (s)
X + y = 180 (according to question x =y)
X + x = 180
2x = 180
X = 90
(c) – (p)
X + y = 90 (according to question x =y)
X + x = 90
2x = 90
X = 45
(d) – (q)
X + y = 180 (linear pair of angles) ……………………….(i)
X – y =60 (according to question) …………………….. (ii)
Adding (i) and (ii) we get,
2x = 240
X = 120
Now putting this in (ii) we get,
Y = 120 – 60 = 60
