The expression can be written as : sin(π/3 - π/7)

<h3>what are trigonometric functions?</h3>

Trigonometric functions are functions that gives the relationship between the sides and angles of a triangle.  

some of the trigonometric functions are sine, cosine, tangent.

Analysis:

Let A = π/3

     B = π/7

If sin(A-B) = sinAcosB - cosAsinB

then sinπ/3cosπ/7 - sinπ/7cosπ/3 = sin(π/3 - π/7)

Which best explains if quadrilateral WXYZ can be a parallelogram?
nekit [7.7K]

A quadrilateral in which opposite sides are parallel is called a parallelogram. The correct option is A.

<h3>What is a parallelogram?</h3>

A quadrilateral in which opposite sides are parallel is called a parallelogram. Thus, a parallelogram is always a quadrilateral but a quadrilateral can or cannot be a parallelogram.

For a parallelogram, the pair of opposite sides are equal and parallel. Therefore,

1.)  For the first pair.

(x+8) = 15

x = 7

2.) For the second pair

(x+2)=(2x-5)

x + 2 = 2x - 5

2 + 5 = 2x - x

x = 7

(x+2) = (7+2) = 9

Since the measure of the pair of opposite sides is 15 units, the pair of the other two sides measure 9 units.

Hence, the correct option is A.

The complete question is mentioned in the below image.
