in the adjoing figure, abcd is a trapezium. If angle a : angle b =5:7

1.	in the adjoing figure, abcd is a trapezium. If angle a : angle b =5:7 ,b = 3x+ 11 and c = 5x -31 , then find all the angles in the trapezium
Answer» Step-by-step explanation: nth term of an A.P (an) = PN + q To find: Common DIFFERENCE (d) Proof: We KNOW that, an = a + (n – 1)d ⇒ pn + q = a + (n – 1)d [given] ⇒ pn + q – a = (n – 1)d

Answer»

Step-by-step explanation:

nth term of an A.P (an) = PN + q

To find: Common DIFFERENCE (d)

Proof: We KNOW that,

an = a + (n – 1)d

⇒ pn + q = a + (n – 1)d [given]

⇒ pn + q – a = (n – 1)d
