Answer:

x = 27

Step-by-step explanation:

Supplementary angles add up to 180 degrees

65 + 5x - 20 = 180

45 +5x = 180

5x = 135

x = 27

If the 4th term of an A.P is 11 and sum of 4th and 5th term is 25. Find the common difference?

ira [324]

Answer:

$3$

Step-by-step explanation:

4th term+5th term = $25$

5th term = $x$

4th term = $11$

$11+x=25$

$x=25-11$

$x=14$

5th term= $14$

Common difference = 5th term - 4th term

$14-11$

$=3$
