Question

calculate the magnitude of x in the given triangle ​

Answer 1

Answer:

80°

Step-by-step explanation:

exterior angle = sum of interior opposite angle

so, 140° = 60° + x

x = 140° - 60°

= 80°

Answer 2

Given :

• Angle A = 60°

• Angle B = x

• Exterior angle C = 140°

To Find :

$\colorbox{black}{\colorbox{red}{\colorbox{white}{Value\:Of\:x}}}$

Solution :

Let's begin ,

To Find value of x , As we know

$\rightarrow$

of two interior angles is equals to one opposite exterior angles ,

Therefore,

According to the question :

$\rightarrow$We have one interior angle and one exterior angle which is opposite to it..

So, we can easily find the other interior angle by :

$\sf\implies$ 140° - 60°

$\sf\huge\implies$ 80°

Hence, the value of x is 80°
