Answer:

The answer to your question is below

Step-by-step explanation:

Question 1.

We have the opposite side and the adjacent side so use the tangent to find x.

             tan Ф = [tex]\frac{opposite side}{adjacent side}[/tex]

Substitution

             tan Ф = [tex]\frac{12}{20}[/tex]

              Ф = 30.96° = x

Question 2.

Letter A is the correct answer

Letter B is incorrect because the cylinder does not have a height of 15 mm

Letter C is incorrect because of the radius of the sphere is not 6 mm

Letter D is incorrect because the radius of the sphere is not 6 mm and the height of the cylinder is not 15 mm.

Question 3.

To solve this exercise we use the trigonometric function tangent

                tan Ф = [tex]\frac{opposite side}{adjacent side}[/tex]

Solve for opposite site

                 Opposite side = Adjacent side tanФ

                 Opposite side = 30 tan 80

                  d = 170.14 ft

Question 4

To find the sine, first we must calculate the opposite side

                         c² = a² + b²

                          a² = c² - b²

                          a² = 4² - 3²

                           a² = 16 - 9

                           a² = 7

                           a = [tex]\sqrt{7}[/tex]

sin A =  [tex]\frac{\sqrt{7}}{4}[/tex]

sin A = 0.6614
