When do you need to Approximate the height of the triangle to 3 decimal places?
When you require that degree of accuracy in the answer: no more and no less.
What is the perimeter and area of an equilateral triangle with a side of 8?
Perimeter of equilateral triangle: 24 units Area of equilateral triangle: 27.713 square units rounded to three decimal places
What are the angles and area of a triangle with sides of 2.6cm by 2.85cm by 4.7cm?
Using the cosine rule angles of the triangle are: 119.10 degrees, 31.99 degrees and 28.91 degrees all rounded to two decimal places. Using sine area formula its area is: 3.24 square cm rounded to two decimal places.
What is the area of the quadrilateral ABCD when AB is 0.38cm BC is 0.69cm and AD is 0.42cm with angles ABC 109 degrees and BAD 123 degrees?
Form two triangles from diagonal A to C and by finding the areas of each triangle they will add up to 0.305 square cm rounded to three decimal places.
What is the area of an equilateral triangle with a side of 5m?
Area = 0.555*sin(60) = 10.825 square m to 3 decimal places
What kinda of triangle has 12.42ft 9.5ft and 8ft?
If 12.42 ft has been rounded to 2 decimal places then it is a right ange triangle
What does 1.905 Round to by decimal?
Depends what decimal place you wish to round it to. For example, to no decimal places it is 2, to one decimal place it is 1.9, to two decimal places it 1.90 (however it is not entirely necessary to write the zero).
Name all types of triangles for which the point of concurrency is inside the triangle?
The answer depends on what point of concurrency you are referring to. There are four segments you could be talking about in triangles. They intersect in different places in different triangles. Medians--segments from a vertex to the midpoint of the opposite side. In acute, right and obtuse triangles, the point of concurrency of the medians (centroid) is inside the triangle. Altitudes--perpendicular segments from a vertex to a line containing the opposite side. In an acute triangle, the point of concurrency of the altitudes (orthocenter) is inside the triangle, in a right triangle it is on the triangle and in an obtuse triangle it is outside the triangle. Perpendicular bisectors of sides--segments perpendicular to each side of the triangle that bisect each side. In an acute triangle, the point of concurrency of the perpendicular bisectors (circumcenter) is inside the triangle, in a right triangle it is on the triangle and in an obtuse triangle it is outside the triangle. Angle bisectors--segments from a vertex to the opposite side that bisect the angles at the vertices. In acute, right and obtuse triangles, the point of concurrency of the angle bisectors (incenter) is inside the triangle.
What is the length of the apothem of a regular hexagon with 10 cm sides?
The hexagon will consist of 6 equilateral triangles of 3 equal sides of 10 cm and the apothem will divide the triangle into 2 right angle triangles with a base of 5 and an hypotenuse of 10 and so by using Pythagoras' theorem the height of the triangle which is the apothem works out as 5 times square root of 3 or about 8.66 cm rounded to 2 decimal places.

What are the angles in a triangle that has sides of 123cm 79cm and 97cm?
Using the cosine formula for triangles the opposite angles of the given sides are 88.05 degrees, 39.93 degrees and 52.02 degrees respectively all rounded to two decimal places.
How to multiply ans divide by powers of ten?
To multiply by 10k move the decimal point k places to the right - if necessary add 0s after the last digit. To divide by 10k move the decimal point k places to the left - if necessary add 0s between the decimal point and the first digit.
