Answer:
The correct option is B
Step-by-step explanation:
Given information: ∠F=32°,∠D=54° and DF=18m.
According to the angle sum property of triangle, the sum interior angles of a triangle is 180°.
Using angle sum property, we get
Law of sine:
Using law of sine we get
Cross multiply,
Divide both sides by 0.99756405026.
The value of EF is 14.6 m. Therefore the correct option is B.
Answer:
no
Step-by-step explanation:
The Golden number is one of the roots of x²-x-1=0 and x = (1+√5)/2= 1.618
It's just a mathematical constant you can come across in trigonometry, geometry, sequence like Fibonacci and others. You may find it in fractals also and in many shapes in the nature but not necessarily always true.
It might be a coincidence in some natural shapes, but definitely it is a recognized math contant useful in many math domains
2x*(4x^2)*(2x^2+x+7)
8x^3*(2x^2+x+7)
16x^5+8x^4+56x^3
Hope this helps :)
The shaded part’s area would be 135 in
