Question

find the value of x in figure is??
a)230°
b)100°
c)120°
d)150°​​

Answer 1

Answer :-

The value of x in the figure is 115°(✓).

120° + x + (x + 10) = 360°

120° + 115° + (115° + 10) = 360°

Hope it's correct and helpful........!!

Answer 2

Given,

The three angles are = x , 120° and (x+10°)

To find,

The measurement of angle x.

Solution,

We can simply solve this mathematical problem by using the following mathematical process.

From the given diagram, it is clear that the given three angles are formed around a point. And, we know that angles around a point always add up to 360°.

Thus, we can get :

x + 120° + (x+10°) = 360°

2x+130° = 360°

2x = 360° - 130°

2x = 230°

x = 230°/2

x = 115°

(This will be considered as the final result. This value of x will satisfy the condition of producing 360° as the sum of the given angles around a point.)

Hence, the value of x is 115°
