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 the third side of the triangle when two sides are know?
Find the square root of one side squared plus the second side squared.
If 48 cm and 54 cm are the lengths of two sides of the triangle what is the range of possible values of the third side?
The sum of the 2 smallest sides of a triangle must be greater than the length of its longest side
How do you find the length of the third side of a right angled triangle?
a2 +b2 = c2 (c is the longest side/or hypotenuse)
What equation do you use to find the adjacent side length of a triangle if you know the hypotenuse and the opposite side?
Third side = sqrt(hyp2 - opp2)

How do you find the value of x for a triangle?
It all depends on which aspect of the triangle you are being asked to find and what values you already have. If you wish to find an angle, certain values must already be known and you can use trigonometry to find X. If you are asked to find the length of a side, Pythagoras can be used if the triangle contains a right angle. Remember, the angles inside a triangle always add up to 180 no matter what, so if you have two angles and simply wish to find the third, all you need to do is find the remaining difference.
How do you find the third side of the triangle when two sides are know?
Find the square root of one side squared plus the second side squared.
A triangle has a perimeter of 42in the lengths of two sides of the triangle are 13in and 16in find the length of the third side?
13 in
If 48 cm and 54 cm are the lengths of two sides of the triangle what is the range of possible values of the third side?
The sum of the 2 smallest sides of a triangle must be greater than the length of its longest side
How do you find the side length of a right triangle if you have one side length?
One side is not enough. For a right triangle the third side can be calculated by Pythagoras' Theorem if you know the length of any two sides.
How do you find the length of the third side of a right angled triangle?
a2 +b2 = c2 (c is the longest side/or hypotenuse)
If 2 sides of a triangle are 6 and 8 what is the range of permissible values for the length of the third side?
3, 2, 10, 6
What equation do you use to find the adjacent side length of a triangle if you know the hypotenuse and the opposite side?
Third side = sqrt(hyp2 - opp2)
What is the length of the third side of an equilateral triangle have?
The length of the third side of an equilateral triangle is the same as the lengths of both of the other two sides.
How do you find if the lengths of a shape make a triangle?
If (and only if) the length of each pair of sides is greater than the third side, then it is possible to make a triangle.
What is the formula for perimeter of a right triangle when one side is missing?
Surely you know how to find the third side of a right triangle, when you know the lengths of the other two. Find it, and then add up the lengths of the three sides to get the perimeter.
