Question

Pls answer this question

Answer 1

The value of x is 65

$117 + 131 + 142 = x + 2x + 3x$

$390 = 6x$

$x = 65$

Now

$x = 65$

$2x = 2 \times 65 = 130$

$3x = 3 \times 65 = 195$

So the angles are 65 , 130 and 195 respectively ....

Pls mark me as brainliest and follow me.......

Answer 2

Sum of all angles in hexagon= 720°

• 117 + 131 + 142 + 2x + 3x + x = 720
• 390 + 6x = 720
• 6x = 720 - 390
• 6x = 330
• x = 55° = Answer (a)

To find unknown angles

• 2x = 2 × 55 = 110
• 3x = 3 × 55 = 165
• Answer (b)
