Given the hypotenuse and the base ...
-- divide the (base) by the (hypotenuse); get a number less than '1'.
-- the number is the 'cosine' of the elevation angle.
-- either take the cos-1 of the number on a calculator, which is the angle
OR
-- look up the number in a table of cosines and see what angle it represents.

How do you find the area of the right angle triangle given the base hypotenuse and perimeter?
It is: perimeter minus hypotenus+base = height Area = 0.5*base*height
What are difference between the sides of a right angle?
The side of a triangle that is opposite to 90 degree angle is called hypotenuse. The side that is opposite to the given angle (The angle that is under calculations) is called opposite. The side that is adjacent with the given angle is called base.
How to measure length of two sides height diagonal of a right angle triangle where all degrees of angle and length of base given?
The answer depends on whether the base is one of the legs of the right angle or the hypotenuse. Also, a triangle cannot have a diagonal.
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..
How do you find the base of a right triangle when only the height is given?
Use trigonometry if another angle is given. Use Pythagoras' theorem if the hypotenuse is given. Multiply the area by 2 and divide it by its height if the area is given. Or simply measure it.

What is the sin of angle B if the angles are 5 12 and 13?
This is a classic Pythagorean triangle. Although you have given the side lengths, you have NOT given a letter to correspond , with the given side. However, Let 12 be the adjacentr side (base) Let '5' be the opposite side ( perpendicular ) Let '13' by the hypotenuse. Sin(Angle) = opposite / hypotenuse = 5/13 Angle = Sin^(-1) 5/13 = 22.619... degrees. NB This is the angle between the hypotenuse and the base(adjacent) Now 'swopping' things around , we take the angle between the hypotenuse and the perpendicular (opposite) . This now becomes perpendicular(adjacent) and the base becomes the opposite. Hence Sin(angle) = 12/13 Angle = Sin^(-1) 12/13 = 67.380.... degrees. The angle at the 'top' of the triangle. Verification. ' 90 + 67.380... + 22.619... = 180 ( allow for calculator decimals).

Can base of triangle is greater than its hypotenuse?
No because the hypotenuse of a right angle triangle will always be its longest side.
A segment from a vertex that forms a right angle with a line containing the base?
hypotenuse

What is the relationship between the angle of elevation and the highest point?
If the base of the elevation is at a distance d from the observer, then the highest point is at a height = d*tan(angle of elevation)
Real life examples of adjacent angles?
In a right angle triangle the adjacent angle is at the base of the hypotenuse and next to the right angle
Can you find the 2 sides of a triangle if you only know the length of the hypotenuse and the angle between the hypotenuse and the base line?
Yes. If c is the length of the hypotenuse, and alpha is the angle between the hypotenuse and the base. If we say a is the length of the side opposite angle alpha and b is the length of the adjacent side, then the lengths a and b are as follows: a=h*sin(alpha) b=h*cos(alpha)
What is the area of a right angle that has a base of 3 inches height of 4 inches and a 5 inch hypotenuse?
The area of a right angle that has a base of 3 inches height of 4 inches and a 5 inch hypotenuse is: 6 square inches.
