Question

find the value of x in this figure​

Answer 1

Step-by-step explanation:

As ∆ is isosceles triangle

therefore,

40° = x°

40° = 40°

( A ) 40°

Answer 2

Answer :-

• The value of x is 40°. [ Option. a ] is correct.

Step-by-step explanation :-

To Find :-

• The value of x

Solution :-

Given that,

• The triangle is an Isosceles triangle.
• In triangle one of the equal angle is 40°

According the question,

As we know that,

The base angles of an Isosceles triangle are equal. So,

=> One base angle = Other base angle

=> 40° = Other base angle

=> 40° = 40°

Then,

• The value of x is 40°.
