How do you find the hypotenuse of a right triangle using sine?
The sine of an angle theta that is part of a right triangle, not the right angle, is the opposite side divided by the hypotenuse. As a result, you could determine the hypotenuse by dividing the opposite side by the sine (theta)...
sine (theta) = opposite/hypotenuse
hypotenuse = opposite/sine (theta)
...Except that this won't work when sine (theta) is zero, which it is when theta is a multiple of pi. In this case, of course, the right triangle degrades to a straight line, and the hypotenuse, so to speak, is the same as the adjacent side.
What is an open sentence that is true for any numbers?
It's for a crossword puzzle. It has 8 letters and the 6th letter is an R.
Determine where an exhausted Paul would be after walking 739 units on the unit square?
Assuming he is walking along the perimeter, he is one unit short of returning to his starting point for the 184th time.
How tall will something appear to be . If we know actual height and distance the object is from you?
If the actual height is h and the distance is d, then it will subtend an angle of arctan(h/d).
What is the trigonometric values 82 degrees and 12 minutes using 3 major functions?
sin(82.2) = 0.9907
cos(82.2) = 0.1357
tan(82.2) = 7.3002
The principal solution for sin(A + 5) = cos(3A - 25), with angles measured in degrees, is A = 15 degrees.
What are at least facts or more regarding the properties of an equilateral triangle?
1 It has 3 equal sides
2 It is a regular polygon
3 It will tessellate
4 It has 3 equal interior angles of 60 degrees
5 It has 3 equal exterior angles of 120 degrees
6 It has a perimeter which is the sum of its 3 sides
7 It has an area which is 0.5*base*height
8 It can also be calculated as 0.5*side2*sin(60) equals area
9 It has the same centre when enscribed by a circle
10 It has an infinite amount within a crcle
11 It can be the base of a pyramid
12 It can be used with Pythagoras' theorem
13 It can be plotted on the Cartesian plane
14 It has 3 lines of symmetry
15 It can be be doubled up into a quadrilateral
16 It is possible to find its properties given just 1 side length
17 It has no diagonals
18 It can be congruent or similar to other equilateral triangles
19 It is a 2 dimensional shape
20 It has rotational symmetry of order 3
Which mathematician discover number system?
Number systems have been used since pre-historic times. Basic arithmetic probably preceded human beings: for example when a pack of animals would determine whether their numbers were greater than those of their enemies and so decide whether to attack or escape.
The modern formal number system is based on definitions by Richard Dedekind in the second half of the nineteenth century.
How do you make a 3d model of Qutub Minar?
Make a Qutubminar by folding 2 chart papers and giving it a accurate shape then paint it properly and then cut different shapes of flowers to show the steps after that put that on the plyboard so that it will be strong and heavy to hold and can be seen in the lab and then show some greenery and it will be perfect all the best friends do it properly when I have to find for it was so hard but this is my creativity so if u like this make it
What is the feet mark next to the degree mark trigonometry?
A degree is divided into 60 minutes and each minute is divided into 60 seconds. It would mean 54 degrees and 28 minutes. You often find this nomenclature when talking about degrees of latitude and longitude.
How do you find the sides of a right triangle?
Use Pythagorean theorem if you have a right triangle with legs a and b and hypotenuse c. a^2+b^2=c^2 a=sqrt(c^2-b^2) it is possible to find b and c in a similar way.
If the push-rod moves from x1 equals 0 m to x2 equals 14 m how much work did the servomotor do?
The Answers community requires more information for this question. Please edit your question to include more context. The answer depends on the resistance offered by the push-rod.
You want one clamp on one side of the center of the glass and the other clamp on the other side of the center of the glass witrh both equal distance awy from the center.
That is because then both clamps take the same weight ( 1/2 each). I f they are not centered one wil carry a much higher load and also if both are on the same Sid ethe glass will not be centered.
You should put the clamps near the ends as it will easier to have it level over the greatest distance
