How do you find the geometric mean of a proportion?
When the means of a proportion are the same number, that number is called the geometric mean of the extremes. then cross-multiplying gives x2=pq . Taking the square root of both sides, we get x=√pq as the geometric mean of p and q .
What kind of triangle is 30 60 90?
special right triangle
The 30-60-90 triangle is called a special right triangle as the angles of this triangle are in a unique ratio of 1:2:3. Here, a right triangle means being any triangle that contains a 90° angle.
What are the sides of 30 60 90 triangle?
30°-60°-90° Triangles The measures of the sides are x, x√3, and 2x. In a 30°−60°−90° triangle, the length of the hypotenuse is twice the length of the shorter leg, and the length of the longer leg is √3 times the length of the shorter leg.
What is the formula of mean proportion?
In Mathematics, the mean proportion between two terms of a ratio is calculated by taking the square root of the product of two quantities in a ratio. For example, in the proportion p:q :: r:s, we can calculate the mean proportion for the ratio p:q by calculating the square root of the product of the quantity p and q.
What is the mean proportional between 234 and 104?
Answer: The mean proportional between 234 and 104 is 156.
Is a right triangle proportional?
If the lengths of the hypotenuse and a leg of a right triangle are proportional to the corresponding parts of another right triangle, then the triangles are similar. (You can prove this by using the Pythagorean Theorem to show that the third pair of sides is also proportional.)
