Short leg= hypotenuse/2
hypotenuse= short leg*2
long leg= short leg * the square root of 3
It is: 7.5*sin(30) = 3.75 meters
No, because 8 isn't a factor of 30.
90
A right triangle. All the angles of a triangle add up to 180. 30+60+x=180. subtract 30 from both sides, then 60 from both sides and x=90
There are many theories and formulas that can be applied to find the length of each of the sides of a triangle. The most common is the Pythagorean Theorem: a2+b2= c2 . The letters: "a , c" are the two legs. The hypotenuse is the letter "c". For a 30-60-90 triangle you can use a special formula, as well as a 45-45-90 triangle.
isosceles triangle
If the ratio of the three sides are 1:√(3):2, it's a 30-60-90 triangle
No because it does not comply with Pythagoras' theorem.
Let the two sides of the right-angled triangle be a and b. Given that the perimeter is 30 cm, we have a + b + 13 = 30. Since the triangle is right-angled, we can use the Pythagorean theorem: a^2 + b^2 = 13^2. We now have a system of two equations that can be solved simultaneously to find the values of a and b.
Zero. The two shorter sides together make 70 metres, so they lie flat against the longest side. Really, there is no triangle. If the 3 sides actually make a triangle, you can use Heron's formula - look it up - to find the area.
The fact that it has a 30 perimeter tells you nothing about the triangle's angles and very little about the lengths of its sides. The name, if it has any, is indeterminate.
No. But they can be the lengths (not leangths!) of the three sides.
