Question

Please answer the question attached below. Find the value of x.

Answer 1

Answer:

Step-by-step explanation:

ANSWER:-

In Triangle ACO,

If we consider angle AOC as A,

We are already given 2 angles

40 degree and 100 degree.

Now by Angle sum property:-

A+40+100°=180°

A=180°-140°

A= 40°

Now in Triangle OXB,

Angle XOB will be 40°

(Vertically opposite angles with angle AOC or A)

So,

Again by Angle sum property,

x+110°+40°=180°

x=180°-150°

x= 30° is the answer.

MORE TO KNOW:-

• This question is based on Angle sum property of Triangle
• All three sides of angle of Triangle must be equal to 180°
• The angles used is
• LINEAR PAIR
• VERTICALLY OPPOSITE ANGLES.

Answer 2

Answer:

x=30°

Step-by-step explanation:

in ∆AOC

angle(oac+aco+AOC)=180°

40°+100°+AOC=180°

angel AOC=40°

AOC=XOB (vertically opp angles)

now by using sum of all angles in ∆XOB

we will get X=30°
