x = 50°

Step-by-step explanation:

sum of all angles of a quadrilateral is 360°

so, the other unknown angle be y

=》y + 40° + 110° + 80° = 360°

=》y + 230° = 360°

=》y = 360° - 230° = 130°

and the unknown angle + x = 180°

( because they for linear pair )

so, x + y = 180°

x + 130° = 180°

x = 180° - 130° = 50°

hence, x = 50°

hey i’m new i won’t be answering any questions now bye peeps see you next time

the answer is:

the correct option is the option b.

to calculate the surface area of the right cylinder, we need to use the following formula:

from the picture we know that:

so, substituting and calculting we have:

hence, we have that the correct option is the option b.

have a nice day!
