Question

in figure find value of x​

Answer 1

Step-by-step explanation:

As you can see there is a triangle.

Lets mention each of them with A,B,C

So the first uppermost angle can be Angle A

And as we can see it is forming a straight angle with 110° of angle

110° + x = 180°

x = 180° - 110°

x = 70°

Angle A = 70°

So the first rightmost angle can be Angle A

And as we can see it is forming a straight angle with 120° of angle

120° + x = 180°

x = 180° - 120°

x = 60°

Angle B = 60°

So as we know that sum of angles of any triangle is 180°

Angle A = 70°

Angle B = 60°

Angle C = ??

70° + 60° + C = 180°

C = 180° - 130°

C = 50°

Now all the three angles are been found.

So we can find x by seeing that it is straight angle.

x + 50° = 180°

x = 180° - 50°

x = 130°

Therefore value of x is 130°
