How do you use sine cosine and tangent?
They are used to find the angle or side measurement of a right triangle. For example, if 2 sides of a right triangle have known values and an angle has a known measurement, you can find the third side by using sine, cosine or tangent.
How do you find values for the third side of a triangle?
Perimeter -2 known sides = 3rd side 180 -2 known angles = 3rd angle
How do you find the side length on a triangle with one angle given?
To find side lengths on a triangle, you need to know at least one of the sides. The possible combinations for solving* a triangle are: side, side, side; side, angle, side; angle, side, angle; angle, side, longer side. *To solve a triangle is to find the lengths of all the sides and the measures of all the angles.
How do you find the angle opposite of the hypotenuse of a triangle with all three sides known?
The only triangle that has a hypotenuse is a right-triangle. The hypotenuse is the side opposite the right angle, so the angle is always 90 degrees. In this case, if you're just finding the angle then you don't need to know what the side lengths are.
How do you find the area of an isosceles triangle with 2 equal sides and 1 angle?
It really depends on the angle. If the angle is at the point where the two equal sides intersect then you can divide the triangle into two equal parts (forming a right angle with the base), divide the angle by two, then use the following equation(side*arccos(your angle/2))*((side*arcsin(your angle/2)))if the angle is not where the two equal sides intersect then you can divide the triangle into two equal parts (from the point where the two equal sides intersect down to a right angle with the base) then use the following equation.(side*arcsin(your angle)*(side*arccos(your angle))
How do you find the third side of a triangle when two sides and angle are known?
Depends on the Triangle. Right triangles with a 90 degree angle: http://en.wikipedia.org/wiki/Pythagorean_theorem
How do you find the length of a side of a triangle which is not a right angled triangle given two lengths and an angle?
Depending on which sides and angle are known you would use one of the trigonometry functions.
How do you use the altitude to find the length of a right angle?
If 2 sides are known then use Pythagoras' theorem to find the 3rd side of a right angle triangle.
How Pythagorean theorem is used?
If two sides of a triangle with a right angle are known, the Pythagorean Theorem can help you find the third one. It can also be used to verify whether a certain triangle is, indeed, a right triangle (if the three sides are known).
When do you use the Law of Cosines?
We use the law of Cosines to be able to find : 1. The measure of the third side, when the measure of two sides and the included angle of a triangle ABC are known. 2. The measure of any angle, when the measure of the three sides of a triangle ABC are known.
How do you use sine cosine and tangent?
They are used to find the angle or side measurement of a right triangle. For example, if 2 sides of a right triangle have known values and an angle has a known measurement, you can find the third side by using sine, cosine or tangent.
What is given two sides and the included angle?
The cosine rule which is: a2 = b2+c2-2*b*c*cosine A This is used to find the third side of a triangle when the two other sides are known along with the angle between them. Used when the triangle is not a right angle.
If three sides of triangle are 8cm 6cm 10cm Then find largest angle?
It is a right angle triangle and its largest angle is 90 degrees
Who uses cotangent?
The cotangent is used when you want to find an unknown angle in a right angled triangle when two sides (not the hypotenuse) and the included right angle are known.
How do you find values for the third side of a triangle?
Perimeter -2 known sides = 3rd side 180 -2 known angles = 3rd angle
Is there Only One Answer To The Pythagorean Theorem?
Pythagoras' theorem is used to find any of the 3 sides of a right angle triangle if the 2 other sides are known.
How do you find the side length on a triangle with one angle given?
To find side lengths on a triangle, you need to know at least one of the sides. The possible combinations for solving* a triangle are: side, side, side; side, angle, side; angle, side, angle; angle, side, longer side. *To solve a triangle is to find the lengths of all the sides and the measures of all the angles.
