Question

Two adjacent angles of a parallelogram are (2x+50)°and (3x-10)°.The value of x is. A. 28 B. 32 C. 36 D. 42​

Answer 1

Answer:

• options B.32

Step-by-step explanation:

We know that sum of adjacent angles of a parallelogram is 180o (2x+25)o + (3x-5)o

= 180o 5x + 20

= 180o 5x

= 180o-20o 5x = 160o x

= 160o/5 = 23

Answer 2

Step-by-step explanation:

Let ∠A = (2x + 25)°, ∠B = (3x - 5 )°

Since the sum of any two adjacent angles of a parallelogram is 180°, ∠A + ∠B = 180° (2x +

25)° + (3x - 5)° = 180° 5x + 20° = 180° 5x = 180° -

20° 5x = 160° X = 160/5 = 32° So, Value of x is

32°.
