How do you calculate square meter of tringle?
It depends on what information you do have about the triangle. There are different equations depending on whether you know the lengths of three sides, the lengths of two sides and the measure of the included angle, the length of one side and the perpendicular distance to the other vertex (base and height).
How do you use sine in math?
The sine function is used in trigonometric calculations when attempting to find missing side lengths of a right triangle. The sine of an angle in a triangle is equal to the length of the side opposite of that angle divided by the length of the hypotenuse of the triangle. Using this fact you can calculate the length of the hypotenuse if you know an angle measure and the length of one leg of the triangle. You can also calculate the length of a leg of the triangle if you know an angle measure and the length of the hypotenuse.
How can you calculate height of a pyramid by measuring the length of its shadow?
By means of trigonometry if you know the angle of elevation or by comparing it with a nearby object if you know its height and shadow length.
How do you calculate the length of the opposite and adjacent sides in a right angle triangle if you know the length of the hypotenuse and the angle between the adjacent and hypotenuse?
the sides can be found out by using trignometry.. sines and cosines.. sine of an agle is perpendicular/hypotenuse cosine of an angle is base/hypotenuse..
