In degree measure, the angles pi/3,pi/4 , and pi/2 are respectively: A. 60, 45, 90 B. 30, 45, 90 C. 45, 60, 90 D. 60, 30, 90 (al
aev [14]
<span>Solution :-
The value of pi expressed in radians and its equivalent degree is = 180 degree
Hence, the value of pi/3 = 180/ 3 = 60 deg
similarly, the value of pi/3 = 180/4= 45 deg
similarly, the value of pi/2= 180/2= 90 deg
Ans :-
The angles of pi/3, pi/4, pi/ 4 is = 60, 45, 90 degree respectively. Hence the right option is answer is A.</span>
Standard form is the way regular numbers are written.
Example: three plus sixty one times two in standard form is 3+61×2
Complete question :
The tower is 10.00 m tall, and the angle of depression from the top of the tower to the point on the ground is 22°How far is the point from the base of the tower.
Answer:
4.04 meters
Step-by-step explanation:
To obtain the distance between baso of tower and point P on the ground as shown in the solution diagram :
Using trigonometry :
Tan θ = Opposite / Adjacent
Tan 22° = x / 10
0.4040262 = x / 10
0.4040262 * 10 = x
x = 4.04
Hence, distance between base of tower and point P on the ground is 4.04 meters
Answer:
Minimum - 46.4
First quartile - 48.8
Third quartile - 53.2
Median - 50.4
Maximum - 55.9
Step-by-step explanation:
If you write all the numbers down on a piece of paper and start crossing out from the beginning and end Ex. cross out 46.4 and 55.9 until you get to the middle (median) thats how you figure the median out. Continue to do that until you find the first quartile, and last quartile. The maximum and minimum are easy to find those are the biggest and smallest number in the group. To find the first and last quartile, you would do the same thing to find the median just do it from the median and go to the beginning or the end depending on which one you find first. Hope this helps! I learned how to do the crossing things from my old school :)
You just divide the distance travelled by the time like so: 145mi/2.5h and get 58mph. You can convert the 145mi into meters and 2.5h into seconds (145mi is approximately 233345m; 2.5h is 9000 seconds) and get an approximate speed of 26m/s if you want to convert to SI units.
