Question

maths problem please solve this​

Answer 1

EXPLANATION:-

2x+60+3x-40=180              [LINEAR PAIR]

5x-20=180

5x=200

x=200/5

x=40

So the value of x is 40

Answer 2

Answer:

According to the diagram, the angles marked are formed on a straight line, which form a linear pair.

According to geometry, a linear pair adds up to 180 degrees and are supplementary.

Hence, applying that concept we get:

⇒ ( 2x + 60 ) + ( 3x - 40 ) = 180

⇒ 5x + 20 = 180

⇒ 5x = 180 - 20

⇒ 5x = 160

⇒ x = 160/5

⇒ x = 32°

Hence the value of 'x' is 32°.
