sin = opposite/hypotenuse
sin 40° = 12/x
Cross multiply.
0.64278760968x = 12
Divide both sides by sin 40°.
x = 18.7 (rounded to nearest tenth).
Answer:
A regular pentagon has 540 degrees and a regular hexagon has 720 degrees and a square has 360 degrees
Step-by-step explanation:
Answer:
The answer is "
".
Step-by-step explanation:
Although the five first players are red, the very first five cards are not spaded as the spad is a black card.
Its chance of the final card mostly on deck being the ace of spades is therefore determined as:

Thus,
here is the necessary chance.
The number of sides is the same as the number of lines of symmetry and the order of rotational symmetry.
So, a regular decagon would have 10 lines of symmetry.
Length would be 362.5
He width would be 1087.5
Hope this helps :)
