Question

find the value of x in the given figure:​

Answer 1

$\LARGE{ \underline{\underline{ \pink{ \bf{AnSwEr}}}}}$

Value of x = 30°

Step-by-step explanation:

In this Question the property used is Exterior Angle Property .

Exterior Angle Property

• This property states that the Exterior angle of a triangle = Sum of the interior Angles.

• Exterior Angle = 100

• 2 interior angle = x and 70

• So, x + 70 = 100

• x = 100 - 70

• x = 30°

• So, value of x = 30°

Answer 2

$\huge \sf \color{blue}{\underline{\underline{Answer}}} :$

$\large \sf x = 30°$
$\huge \sf \color{blue}{\underline{\underline{Solution}}} :$
We know,
☞ Sum of interior angles = exterior angle
so , x + 70° = 100°
x = 30°
