Question

find the value of x in the figure​

Answer 1

Value of x = 180 - {(180-125)+(180-125)}

= 180 - (55+55 = 110)

= x = 70°

x = 70°

Answer 2

Given:-

• 1 angle = 125°
• 2 angle = 125°

To find :-

• Value of x that is 3rd angle

We know that sum of all exterior angle of triangle is 360°.

${ \large{\mathtt{\bigstar{ \: \: So, \: value \: \: of \: \: x \: \: is :- }}}}$

${\mathtt{\implies{125 \degree +1 25 \degree + x = 360 \degree}}}$

${\mathtt{\implies{250\degree + x = 360 \degree}}}$

${\mathtt{\implies{ x = 360 \degree- 250\degree }}}$

${ \large{ \color{red}{ \boxed{\mathtt{\implies{ x =110\degree }}}}}}$

VERIFICATION

=》 125° + 125° + 110° = 360°

=》360° = 360°

So, LHS = RHS

Hence, 110° is our correct value of x.
