Need some help with trigonometry. Last question answered by bots.

See below for answers and explanations

Step-by-step explanation:

First, find the missing side using the Pythagorean Theorem:

c²=a²+b²

65²=a²+16²

4225=a²+256

3969=a²

63=a

Therefore:

sinα = opposite/hypotenuse = 63/65

cosα = adjacent/hypotenuse = 16/65

tanα = opposite/adjacent = 63/16

sinβ = opposite/hypotenuse = 16/65

cosβ = adjacent/hypotenuse = 63/65

tanβ = opposite/adjacent = 16/63

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!
