What are the characteristics of three sides of a right triangle whose angle is 30? For example, the ratio of three sides of a right triangle of 45 degrees is 1: 1: radical 2, what about a 30 ° right triangle?

What are the characteristics of three sides of a right triangle whose angle is 30? For example, the ratio of three sides of a right triangle of 45 degrees is 1: 1: radical 2, what about a 30 ° right triangle?

1: Radical 3:2

What are the properties of a right triangle with an angle of 60 degrees and an angle of 30 degrees?

The right angle of 30 degrees is half of the hypotenuse

How to prove that a triangle with an angle of 30 degrees whose opposite side is half of an adjacent edge is a right triangle

In this paper, we prove this problem by using the method of proof to the contrary: the triangle ABC, AB is the hypotenuse, BC = AB / 2, ∠ BAC = 30o

The hypotenuse of a right triangle is 20 cm, and the length ratio of two right angles is 3:4 My math exercises

Let the length of two right angles be 3x and 4x
Then (3x) 2 + (4x) 2 = 20
9X²+16X²=400
X²=16
X=4
So, 3x = 12, 4x = 16
A: the two right angles are 12 cm and 16 cm long

The hypotenuse of a right triangle is 20 cm, and the ratio of the length of the two right sides is 3:4

Let two right angles be 3xcm and 4xcm,
Then (3x) 2 + (4x) 2 = 202,
The solution is: x = 4 or x = - 4 (omitted),
Then 3x = 3 × 4 = 12 (CM), 4x = 4 × 4 = 16 (CM),
That is, the two right angles are 12cm and 16cm

The hypotenuse of a right triangle is 20 cm, and the ratio of the length of the two right sides is 3:4

Let two right angles be 3xcm and 4xcm,
Then (3x) 2 + (4x) 2 = 202,
The solution is: x = 4 or x = - 4 (omitted),
Then 3x = 3 × 4 = 12 (CM), 4x = 4 × 4 = 16 (CM),
That is, the two right angles are 12cm and 16cm

For a right triangle, the length of the two right sides is 4cm and 6cm respectively. When you rotate around the two right sides, you can get a cone For a right triangle, the length of the two right sides are 4cm and 6cm respectively. Rotating around the two right sides for a circle, you can get a cone. What is the volume of the larger cone?

14 × 4? 2 × 6 × 1 / 3 = 100. 48 cm3
14 × 6? 2 × 4 × 1 / 3 = 150. 72 cm3
So the volume of the larger cone is 150.72 cubic centimeters

Given that the hypotenuse of a right triangle is 6cm, the other two angles are 30 and 60. How long are the other two

If the other two angles of a right triangle are 30 ° and 60 ° respectively, then the right angle side to which the angle of 30 ° is opposite must be half of the hypotenuse (there is in this conclusion book), that is 3 cm. According to the Pythagorean theorem, the length of the other side is 3 and the root sign is 3 cm

The three sides of a right triangle are 50cm, 40cm and 30cm in length. What is the height of the hypotenuse of this right triangle______ Centimeter

30×40÷2×2÷50，
=1200÷50，
=24 (CM);
A: the height on the hypotenuse of this right triangle is 24 cm
So the answer is: 24

There is a right triangle with two right angles of 30cm and 40cm. Its hypotenuse is 50cm. How many centimeters is the height of the hypotenuse?

30×40÷2×2÷50，
=1200÷50，
=24 (CM);
A: the height on the bevel is 24 cm
