Question

find the three angle​

Answer 1

Answer:

x+x+1+x-1=180°(sum of angles on a straight line = 180°)

3x=180°

x=60°

Answer 2

$\sf{Answer}$

Step-by-step-explanation:-

Given in figure We have to find the three angles

If you observe the given figure It forms a linear pair

Linear pair :- If the angles form a linear pair Sum should be equal to 180°

So,

(x -1) + x + x+1 = 180°

x - 1 + x + x +1 = 180°

x + x + x -1 +1 = 180°

3x = 180°

x = 180°/3

x = 60°

Finding angles :-

x- 1 = 60°-1

x -1 = 59°

x = 60°

x + 1 = 60+1

x + 1 = 61°

So, Required angles are 59°,60°,61°

Verification:-

As we know That These angles sum should be 180°

So, we got three angles Their sum should be equal to 180°

59°+60°+61° = 180°

119°+61° =180°

180° = 180°

LHS = RHS

Hence verified
