It is known that the hypotenuse length of a right triangle is 71mm. The degree is 30 degrees, 90 degrees and 60 degrees. How to calculate the length of the other two sides

It is known that the hypotenuse length of a right triangle is 71mm. The degree is 30 degrees, 90 degrees and 60 degrees. How to calculate the length of the other two sides

30 degrees is a special angle. Its corresponding side is equal to half of the hypotenuse, that is 35.5mm. The corresponding side of 60 degrees is three times of the root sign of the half of the oblique edge, that is, 71 times of the root sign of the second half

Given that the area of a right triangle is equal to 50, when the length of right angle sides is ~, and respectively, what is the minimum value of the sum of the two right angles

The two right angles are x, y
Then 1 / 2x * y = 50, X * y = 100, x = 100 / y
The sum of two right angles x + y = 100 / y + y ≥ 2 √ (100 / y) * y = 20, when 100 / y = y, take the equal sign
That is, y = 10, x = 10
When the right angle side length is 10, 10, respectively, the minimum sum of the two right angle sides is 20

If the sum of the two right sides of a right triangle is known to be 4, then the minimum length of the oblique side is equal to____ .

Let two right angles be a, B and hypotenuse C, then a + B = 4, C ^ 2 = a ^ 2 + B ^ 2 = a ^ 2 + (4-A) ^ 2 = 2A ^ 2-8a + 16 = 2 (A-2) ^ 2 + 8 ≥ 8, the minimum value is obtained when a = b = 2

What is the diagonal length of a right triangle?

Equal to the sum of the squares of the two right angles, Pythagorean theorem

If the difference between the two interior angles of a triangle is equal to the third inner angle, it must be a right triangle As the title

Let three inner angles be a, B, C. There is a + B + C = 180 degrees, that is, a = 180 degrees - (B + C) So, 180 degrees - (B + C) = B + C, B + C = 90 degrees, so a = 90 degrees To sum up, there is no lack of conditions,

If the center line on the hypotenuse of a right triangle is equal to the length of the shortest right angle side, then its minimum inner angle is () A. 10° B. 20° C. 30° D. 60°

∵ the center line on the hypotenuse of a right triangle is equal to half of the hypotenuse,
The center line of the hypotenuse is equal to the length of the shortest right angle side,
The hypotenuse of a right triangle is twice that of a short right angle,
Then its minimum internal angle is 30 degrees
Therefore, C

If an inner angle of a right triangle is equal to 30 ° and one of the longer right sides is 3, then the length of the hypotenuse is The length of the bevel is

The length of the hypotenuse is 3 △ cos30 = 3 △ 3 / 2 = 2 √ 3

A right triangle has three inner angles of 30 °, 57 ° and 37 ° respectively. What is the relationship between its three sides? Sorry, it's 90 degrees, 57 degrees, 37 degrees

Honey, what's the sum of the angles in a triangle~~~~

A right triangle has an inner angle of 30 degrees and an inner angle () whose hypotenuse is () times the length of the shorter right angle

60 degrees
2 times

If an inner angle of a right triangle is equal to 30, and one of the longest right angles is 3, then the length of the hypotenuse is

If the short right angle side is x, then the oblique side length is 2x
X^2+9=(2X)^2
X=√3
The length of the oblique side is 2 √ 3
