Question

Find the value of unknown angle x.​

Answer 1

●For figure (b)

➡️The exterior angle of a triangle is equal to the sum of the interior opposite angles.

So, by this logic,

✍100° = x + 60°

=> x = 40°✔

●For figure (c)

➡️Sum of all the angles of a triangle is equal to 180°.

So, applying this logic,

✍2x + 3x + x = 180°

=>6x = 180°

=>x = 30°✔
