Answer:
There will be 19 trees left over after planting.
Step-by-step explanation:
Divide 1384 by 21 which gives you the quotient of 65.90...
Then multiply 65 by 21 which equals 1365
Lastly subtract 1384 and 1365 which gives the answer 19.
The smallest number of seats that both theatres can have us 60
For a right triangle, we have he advantage of using the trigonometric functions like cosine and sine.
If you use cosine function:
cos45 = adjacent/hypotenuse
cos 45 = b/c
c = b/cos 45
If you use sine function:
sin 45 = opposite/hypotenuse
sin 45 = a/c
c = a/sin45
From the choices, the answer is <span>b over cos 45 degrees</span>
