Question

find the size of unknown angle and its answer is x=35°,y=55°​

Answer 1

Answer:

By angle sum property,

40 + 90 + x = 180

so, x= 50

By linear pair,

x + O = 180

so, O = 130

since radius= radius

so, y= z

so, y+ z+ O= 180

by angle sum property

therefore, y= z= 25

Answer 2

$\sf\underline\bold{by\:angle\:some\:property,}$

$\sf\implies 40 + 90 + x = 180$

$\sf\implies 130+x=180$

$\sf\implies x=180-130$

$\sf{\blue{\fbox{\red{x=\:50 \degree}}}}$

so, x= 50

By linear pair,

x + O = 180

so, O = 130

since radius= radius

so, y= z

so, y+ z+ O= 180

by angle sum property

therefore, y= z= 25
