Question

POQ is a straight line. Find the value of $x$

Answer 1

Hey there!

Answer:

x = 22.2

Step-by-step explanation:

Given,

POQ is straight line.

So sum of all angles = 180°

3x - 10 + 2x + 4x - 10 = 180°

9x - 20 = 180°

9x = 180 + 20

x = 200 / 9

x = 22.2

Answer 2

Hey their!

Answer:

x = 22.2 units.

Step-by-step explanation:

We have,

⇒ 3x - 10, 2x , 4x - 10

We know that,

Sum of all the angles on a straight line is 180°.

Therefore,

⇒ 3x - 10 + 2x + 4x - 10 = 180°

⇒ 3x + 2x + 4x -10 -10 = 180°

⇒ 9x - 20 = 180°

⇒ 9x = 180 + 20

⇒ 9x = 200°

⇒ x = 200/9

⇒ x = 22.2 units.
