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

Answer:
42 i think
Step-by-step explanation:
You used 80% I think :)
10(2y+2)= 10.2y+10.2
20y+20-y
2(8y-8)=2.8y-2.8
20y+20-y=16y-16
20y-16y-y=-20-16
3y=-36
36/3y=?
y=-12
76 unit
because added the rectangle size and added the 60 with 16
