Answer:
42. acute
43. obtuse
Step-by-step explanation:
Obtuse: which one of the interior angles measures more than 90° degrees, then the rest are less than ninety.
Acute: all less than ninety and all different.
0.17 is the decimal, answer 3
First, convert 15'66'' to degrees. Every degree is 60' and every minute (') is 60''. Thus, 15' x (1° / 60') = 0.25°and 66'' x (1' / 60'') x (1° / 60') = 0.01833°Add all the measurements in degrees including the 32° from the given. That is, 32° + 0.25° + 0.01833° = 32.268°Rounding the answer to the nearest hundredth gives us 32.27°.
Answer:
Number of trials are 250.
Step-by-step explanation:
A researcher finds 15% of all commuters in a metropolitan area take the train to work.
The researcher polls 250 people in the area to ask them whether they take the train to work or not.
We have tell the number of trials for this binomial experiment.
Researcher will do 250 trials to confirm whether they take the train work and this irrespective of their response.
D. 3
You can use Pythagorean Theorem to figure this out.
a^2 + b^2 = c^2
4 would your b, and 5 would be your c. You would then solve for a.
Also, 3-4-5 triangles are just something that you can always count on. If two sides of a triangle are 3 and 4, you can count on the hypotenuse being 5. On the other hand, if you know the hypotenuse is 5 and you know one of the other sides is either 3 or 4 (let’s say 3, for example) then you know the missing side has to be the other number (which would be 4 in the example i gave).
