 We have the angle between the base and the hypotenuse of the triangle.
 We have the height of the triangle.
 We want to calculate the base of the triangle.
 For this, we use the following trigonometric relationship:
 tan (4.76) = 2 / x

 Clearing x we have:
 x = 2 / tan (4.76)

 x = 24.02 feet
 Answer:

kykrilka [37]

Given:

The equation is

\dfrac{7}{2}n=3n+4

To find:

The properties which is not used from the given options.

Solution:

We have,

\dfrac{7}{2}n=3n+4

Using Multiplication Property of Equality, multiply both sides by 2.

2(\dfrac{7}{2}n)=2(3n+4)

7n=6n+8                    (Distributive Property)

Using Subtraction Property of Equality, subtract 6n from both sides.

7n-6n=6n+8-6n

n=8

From the given options only one property is not used, i.e., Zero Product Property.

Therefore, the correct option is D.
