Question

25) Find the value of x in the given figure R (2x + 60) (3x - 40)​

Answer 1

Answer:

x=32

Step-by-step explanation:

The given angles are in linear pair and linear pair is always 180°.

So, (2x+60)°+(3x-40)°=180°

or, 2x+60+3x-40=180

or, 5x+20=180

or, 5x=180-20

or, x=160/5

or, x=32

Hence, required value of x is 32.

Answer 2

Answer:

32ˣ

Step-by-step explanation:

e

angle 1 + angle 2 = 180

( 2x + 60 ) + ( 3x - 40 ) = 18

To check:

then, 5x + 20 = 180

then, 5x = 180 - 20

then, 5x = 160

What it means?

x = 160 and 5 = 32
