Mathematics

Answer:

x = 2

Step-by-step explanation:

Any lower base angle is supplementary to any upper base angle, then

51x + 3 + 75 = 180

51x + 78 = 180 ( subtract 78 from both sides )

51x = 102 ( divide both sides by 51 )

x = 2

3) The volume of a sphere is 7234.56ft3. Find the diameter.
pashok25 [27]

Answer: 12.001 ft is the radius

Step-by-step explanation:

Volume of sphere is calculated by following formula:

V = 4/3 pi r³

Putting values

7234.56 = 4/3 × 3.14 ×r³

Simplifying

7234.56 = 4.186 ×r³

Rearranging the equation

r³ = 7234.56/4.186

r³ = 1728.28

Taking cube root on both sides

r = 12.001
