Question

in each of the following figures,find the value of x


please give the answer In full explanation​

Answer 1

Step-by-step explanation:

Since, BD and DC are equal.

$\therefore \: \angle{C = 50°}$

Sum of all three angles of a triangle = 180°

$So, \: \angle{A} + \angle{B} + \angle{C} = 180°$

$\angle{A} + 50° + 50°=180°$

$\angle{A} + 100°=180°$

$\angle{A} =180° - 100°$

$\angle{A} =80°$

$\because \: \: x = \frac{1}{2} (\angle A)$

$\therefore \: \: x = \frac{1}{ \cancel2} \times \cancel{80°}$

$x = 40°$

I hope it is helpful

Answer 2

correct answer is 40°

mathematics is the abstract science of number,quantity, and space either as abstract concepts or as applied to other disciples such as physics and engineering
