At a certain distance the angle of elevation to the top of a building is 60 From 40ft further back the angle of elevation is 45 Find the height of the building?
Angle of elevation: tangent angle = opposite/adjacent and by rearranging the given formula will help to solve the problem
Can someone find value of cos20cos40cos80?
cos20 x cos40 x cos80 = 0.0300 radians = 0.125 degrees (the value for radians is given to four decimal places, the value in degrees is exact)
What is Pythagoras's formula?
It's c2=a2+b2 where c is the hypotenuse (longest side), a and b are the other sides, it helps find if it's a right-angle triangle.
What the formula of a parellelogram to find the value of x?
It depends on what x is - an angle, a side, a diagonal, etc
What the only formula you can find the exact value of cosine 30?
Cosine(30) = sqrt(3)/2
What to do when you have the hypotenuse and angle?
For trigonometry if you have the value of the hypotenuse and the angle, it depends what side you are trying to find. If you are looking for the side across from the angle, the formula is sine(angle)=opposite side divided by hypotenuse. If you are looking for the side adjacent to the angle, the formula is cosine(angle)=adjacent side divided by hypotenuse. Hope this helps!
How do you find the exact value with percent error and your result?
To find the exact value you could:use exact values rather than estimates - as inputs;use exact formula instead of approximations,use calculus.There are other methods as well and the choice depends on the circumstances. Then, if Y is your value and E is the exact value,percentage error = 100*(Y - E)/E or 100*(Y/E - 1).

What is the formula to find the measure of each interior angle of a regular polygon?
that's geometry so the formula to find the measure of each interior angle of a regular polygon is: Ia=stands for internal angle Ia=(n-2)180 ---------- n that's the formula.
What is the formula to find interior angles?
there is no fix formula for this..........you have to check that what is given to you in the question. According to the given you have to find the interior angle.
What is the formula to find the length of a right angle triangle?
By using Pythagoras' theorem for a right angle triangle.
Why in right angle triangles is it called Pythagoras theorem when it is in actual fact known before his time?
It is called Pythagoras' theorem because it's impossible to find the exact length of the hypotenuse of a right angle isosceles triangle which is an irrational number in the same way that it is impossible to find the exact area of a circle because the value of pi is also an irrational number.
What is the formula to find the vertex angle?
There is no general formula. You need to measure it or else have a lot more information.
Which formula should you use to find the area of a parallelogram?
There is no exact formula to find the area of a parallelogram * * * * * It all depends on what information you do have. If you know the base length, B, and the vertical height, H, then the area is B*H square units. If you don't know H but know an angle then some trigonometry will enable you to find H.
