Question

Find the value of x in each figure :​

Answer 1

Here, According to the question

AB = BC

Hence, we can say that, $\sf \angle A = \angle C$

And also Because of interior angles

• 30° = $\sf \angle C = \angle A$

Hence, $\purple{ \boxed{ \bf \angle A = x = 30°} }$

For more :

For $\sf \angle B$

Now, we already know that,

In triangle, the sum of all angles is 180°

So,

• $\sf \angle A + \angle B = 180°$

• $\sf 30° + \angle B = 180°$

• $\sf \angle B = 180° - 30°$

• $\purple{\boxed{\bf \angle B = 150°}}$
