Answer 2

Currect Question :

Find the value of x ?

a) 30°

b) 90° $\large{\bf\green{✓}}$

c) 34°

d) 85°

___________________________

Answer : $\large{\bf{b)~90°}}$ $\large{\bf\green{✓}}$Option is correct.

___________________________

Given :-

• $\large\angle$AOD + $\large\angle$COB
• $\large\angle$AOD + $\large\angle$COB $~~$ ${\sf{(Straight~Line)}}$
• $\large\angle$AOD + $\large\angle$COB + $\large\angle$DOC = 180

To find :-

• Find the value of x ?

Solution :-

:$\implies$40° + 50° + x = 180°

$~~~~~$:$\implies$90° + x = 180°

$~~~~~~~~~~$:$\implies$x = 180° - 90°

$~~~~~~~~~~~~~~~$:$\implies$x = ${\sf{90°}}$

$~~~~~~~~~~~~~~~~~~~~$:$\implies$$\large{\underline{\boxed{\pink{\frak{x~=~90°}}}}}$★

$\large\dag$ Hence,

• The value of x = $\large{\bf{90°}}$ $\large{\bf\green{✓}}$
