SOURCE: This is a right angled triangle. A radio mast is

It is not clear which angle you are talking about...

In one case the Hypot = 36/(cos(63)) meters. (about 79 meters)

The other case Hypot = 36/(cos(90-63)) meters (about 40 meters)

If the length of hypotenuse of a right angled triangle is 5cm, its area is 6 sqcm. then the length of the remaining sides are


The Pythagorean Theorem states for a right triangle
A squared + B squared = C squared
where C is the hypotenuse.

if the hypotenuse is 5cm, then the remaining sides have to be 3cm & 4cm

Also called the 3,4,5 right triangle.

How to use tan and cos


In any right angled triangle, for any angle:

  1. The sine of the angle = the length of the opposite side. the length of the hypotenuse.
  2. The cosine of the angle = the length of the adjacent side. the length of the hypotenuse.
  3. The tangent of the angle = the length of the opposite side. the length of the adjacent side.

What is the length of a hypotonuse triangle with legs being 4 and 3


a^2 + b^2 = c^2
a squared + b squared = c squared, where c is the length of the hypotenuse, and a and b are the lengths of the other two sides in a right-angled triangle.

What is the length of the hypotenuse of the right triangle ABC in the figure? A. 5.8 B. 11.0 C. 7.2 D. 6.2


Hi David:
You've got me confused.
A triangle has 3 sides. You have provided 4 lengths and no picture.
The hypotenuse is joins the 2 sides that are the "legs" of the right angle.
The length of the hypotenuse is the square root of the sum of the squares of the sides.
Just apply the "rule" to the appropriate dimensions.
Cheers

Formula to calculate hyportenuse


The formula to calculate the hypotenuse of a right angled triangle is a^2 + b^2 = c^2 or in words, a squared plus b squared is equal to c squared. The most common mistake is that students make the hypotenuse a squared or b squared. The hypotenuse has to be c squared. Thus, when figuring out the sides of a right-angled triangle, always make sure the hypotenuse is the longest side.

For example, a triangle with sides of length 3 and 4, calculate the hypotenuse. Let a be 3 and b be 4. 3^2 + 4^2 = c^2 or 9+16 = c^2, or 25 = c^2. Now take the square root of both sides and we get c = 5.

Given a length of 30 cm on the x axis and a length of 10 cm on the y axis and a angle of 90 at the x/y axis intersection is there a short cut to calculate interior angles and hypot. of the triangle?


Yes, there is shortcut because this is right triangle, so you can use Pythagorean theorem (see picture).
  1. Length of hypotenuse is square root of sum of squares of lengths of other two sides of triangle, which is equal to square root of 30^2+10^2=31.6 cm.
  2. Sin(a)=longer cathetus/hypotenuse=0.949 so a=arcsin(0.949)=71.6 degrees
  3. Finally b=90-a=18.4 degrees.
