Which equation is equivalent to 12+81 . x4 10?
x+ 9 = x + 10
x + 9 = x2 + 20% + 100
x2 + 81 = y2 + 100
x2 + 81= x2 + 20% + 100

8

step-by-step explanation:

the answer is 2/54

step-by-step explanation:

m∠5 + m∠3 = m∠1   is true.

m∠5 + m∠6 = 180 is true

m∠2 +m∠3 = m∠6   is true

m∠2 +m∠3 +m∠5 = 180   is true

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!
