Question

find the value of x in the following figure.....

last one.......​

Answer 1

$\huge\orange{\boxed{\mathscr{\red{An{\pink{\mathbb{Sw{\blue{\mathtt{er}}}}}}}}}}$

Sum of all the angels = 36O°

So, x + 9O° + 12O° = 36O°

=> x + 21O° = 36O°

=> x = 36O° – 21O°

=> x = 15O°

Answer 2

$\sf \Large Solution!!$

$\sf We\:can\:see\:that\:a\:full\:angle\:is\:being\:formed.$

$\sf So,$

$\sf \to 90°+120°+x=360°(full\:angle)$

$\sf \to 210°+x=360°$

$\sf \to x=360°-210°$

$\sf \to x=150°$

Thanks for asking!! :)
