implied triangles are triangles caused by perspective
the building is not a real triangle just looks like one so its an implied triangle
As a mathematical word it is pronounced 'sign'.
As a Ltin word it is pronounced as ' seenay'.
14.5 cm.
What is the measure of the sides of an isosceles triangle if one side equals 12.1?
If one side of an isoceles triangle has a measure of 12.1, then either... 1. One of the other sides is also 12.1. ...or... 2. The other two side as equal to each other but not equal to the known side. In both cases, the unknown side(s) are unknown, because the angles are not stated.

Should you take pre-calc or trig before ap calc?
Yes, you should take both pre-calc and trig before ap calc. Both of those course help lay the fundamentals of ap calc.
How is trignometry used in physics?
Resolving a force into components along mutually perpendicular directions requires the calculation of the cosine and sine of the angle made by the force with one of them.
The resultant of two two forces acting at right angles to one another is in the direction whose tangent is proportional to the forces.
you cant because 7 8 9!! hahahahahaaa lolz it is 33 though.
What is a shape with with two triangular faces and three rectangular faces called?
It's called a rectangular prism
What are cartesian coordinate systems?
For Cartesian coordinates in n-dimensional space there are n axes which are [usually] orthogonal and which meet at a single point called the origin. The coordinates of any point in the n-space are defined by ordered n-tuples whose terms refer to the distances of the point, from the origin, along each of the axes.
What is a 3-dimensional geometric shape with 7 faces and just one pair of parallel faces?
A pentagonal prism.
How would you describe a trapezium?
A quadrilateral, or four-sided plane figure with 1 pair of parallel lines
How do you find SIN in trigonometry?
Many calculators, as well as any modern desktop computer, will have a function to tell you the SIN to many decimal places of accuracy. There are also books with pages of trig functions, and you would look up the angle you want.
To get an approximation with pencil and paper, do this:
1. Start with a horizontal line.
2. Using a protractor, draw the angle crossing your horizontal.
3. Make a right triangle by extending a vertical line that crosses the angled line and the horizontal.
4. Measure the height of the vertical from the horizontal to the intersection with the angled line (the opposite side of the triangle from where your angle is.
5. Measure the hypotenuse (longest side of the triangle).
6. Divide the opposite length by the hypotenuse length.
What are two sides of the right triangle that are not opposite to the right angle?
They are the adjacent and the opposite sides with the hypotenuse being the longest side
There is not enough information to be able to find the last side.
Why are numbers you get in trigonometry never whole numbers but have to be rounded?
Not true.
tan(45) = 1 is a whole number.
sin(0) = 0 and sin(90) = 1 are whole numbers.
So the question is based on nonsense!
What do you think is true of the square roots of a complex number?
I posted an answer about cube roots of complex numbers. The same info can be applied to square roots. (see related links)
