Answer: 10:7
Step-by-step explanation:
40:28=10*7
Hello!
First, find angle BOA on the protractor. To do this, look for point B, point O, and point A.
Now, we see some markings that mark what degree point B and point A are at. Point B is marked at 60 degrees, and Point A 40 degrees.
Now, all that's left to do, is subtract the two measurements.
60 degrees - 40 degrees = 20 degrees
Therefore, your answer is 20.
Hope this helps!

Answer:
sin(D) = cos(E) = (√3)/2
cos(D) = sin(E) = 1/2
Step-by-step explanation:
The mnemonic SOH CAH TOA is intended to remind you of the relationships between trig functions and right triangle sides.
Sin = Opposite/Hypotenuse
Cos = Adjacent/Hypotenuse
For this diagram, this means ...
sin(D) = cos(E) = (13√3)/26 = (√3)/2
cos(D) = sin(E) = 13/26 = 1/2
The answer should be "filtration" because distillation is for liquids. Filtration filters out the unwanted products.
The radius is half of the diameter.
To find the circumference, use the equation C=2(pi)r or C=(pi)d.
r meaning radius. d meaning diameter.
(pi) is about 3.14 or 22/7
