How do you find length of a hypotenuse of a 30 60 90 degree triangle is 7 cm what is the perimeter?

- The length of the other two sides is 7 cosine (60) and 7 cosine (30)
- that is 3.5 and 6.062 cm
- the perimeter = 7 + 3.5 + 6.062 = 16.562 cm

How do you figure out the perimeter of an triangle when you only have a measurement for the hypotenuse?
It is impossible. You need another measurement, such as angle, side length or area etc.
A right triangle has a hypotenuse of length 15 and a leg of length 8 What is the area of the triangle?

How do find the perimeter of a triangle?
The easiest way is if you already have the lengths of all three sides of the triangle. In which case, you simply add their lengths together to acquire the perimeter. However, if you only have the lengths of two sides of a triangle, and it's a right triangle"; you can use the Pythagorean Theorem to determine the length of the third side. Note: Here are some quick definitions of terms that will be used in the following equations. A² will represent the height of the triangle. B² will represent the width of the triangle. C² will represent the hypotenuse of the triangle. The "Hypotenuse" is the longest side of a triangle. A "Right Triangle" is a triangle that has an angle measuring 90°. When using the Pythagorean Theorem; if you're attempting to find hypotenuse of a triangle; you use the formula "A² + B² = C²". That is; you square the two known sides; then add the products. Upon doing that, find the square root of the sum of both numbers, and you have the length of the hypotenuse. Upon finding the missing side's length; add the lengths of all three sides, and the resulting number will be the perimeter of the triangle. If you have the length of one side, and the hypotenuse of a right triangle; and are seeking to find the third side's length; you use the formula "C² - A² = B²" or "C² - B² = A²"; depending on which side your attempting to find the length of. Like in the previous equation, add the lengths of all three sides together to acquire the perimeter.
How do you know the other two sides of right angled triangle if perimeter is 50 cm and hypotenuse is 12 cm?
I spent some time attempting to work this out by algebra and came to the conclusion that there is no (real) solution to this. This triangle does not exist. Rather than my writing a page on it which culminates in a quadratic equation without real roots, I will just point out that the two statements in this question can not both be true! If the hypotenuse (which is the longest side) is 12cm then the perimeter can not be 50cm! There is an error in either the hypotenuse given or the perimeter given. I wish I had spotted this a little sooner. ~ A simple reason why this cannot be a plausible length for the hypotenuse: The hypotenuse's length should be the greatest length in the triangle. If we subtract 12 from 50, we get 38. If the two sides were equal, then one leg's length is 19. 19 is greater than 12.
Where can you find the hypotenuse of a right triangle?
the hypotenuse is the side of the right triangle that is opposite of the 90 degree angle. To figure out the length of the hypotenuse you can use a2 + b2 = c2 (if you know the length of the other two sides) If you don't that you can probably use the sine or the cosine equation. (as long as you know at least one of the angles)
What is the perimeter of a triangle that is attached to a hypotenuse?
That depends entirely on the LENGTH of the hypotenuse !
If the shortest leg of a 30 degree 60 degree 90 degree triangle has length 7 the length of the hypotenuse is?
In general call the shortest side a and remember this is always the side opposite the 30 degree angle. Then the other leg/side has length a(square root 3) and the hypotenuse has length 2a.So in the case of a=7, the hypotenuse has length 14.
The shorter leg of a 30 degree 60 degree and 90 degree triangle is 18 What is the length of the hypotenuse?
18/cos(60) = 36 units in length
A 45 degree-45 degree-90 degree triangle has a hypotenuse of length 11 what is the length of one of its legs?
7.778174593 units, solved with the help of Pythagoras' theorem.
What is the length of the median to the hypotenuse of a right triangle if the hypotenuse is 12 inches in length?
The median to the hypotenuse of a right triangle that is 12 inches in length is 6 inches.
How do you figure out the perimeter of an triangle when you only have a measurement for the hypotenuse?
It is impossible. You need another measurement, such as angle, side length or area etc.
