How to calculate the oblique angle of a right triangle

How to calculate the oblique angle of a right triangle

A / Sina = B / SINB = C / sinc (arbitrary triangle)
C ^ 2 = a ^ 2 + B ^ 2-2abcosb (arbitrary triangle) the degree of any angle of any triangle can be calculated with these two formulas

In a right triangle, if you know the right angle side and the oblique angle side, how to find another right angle side One right angle side is 5, and the hypotenuse is 6,

Pythagorean theorem. The sum of the squares of each side of two right angles is equal to the square of the hypotenuse. Therefore, the other corner is equal to √ 6 ^ 2 - √ 5 ^ 2 = √ 11

A right angle side of a right triangle is 6 meters long, one of which has an oblique angle of 31 degrees. What is the length of the other right angle side and how to calculate it

There are two possible consequences of this problem
1、 The opposite side of the 31 degree angle is 6 meters
Adjacent edge = 6 / tan31: = 9.986m
2、 The adjacent side of the 31 degree angle is 6 meters
Opposite side = 6 Tan 31 o = 3.605 M

Given the two right sides of a right triangle, one side is 3.25 and the other side is 41. Find two oblique angles Give me this formula, too,

The angle of the right angle side pair of length 41 is 85.467738 degrees (acttan (41 / 3.25), and the other is 4.532262 degrees

Given the two right angles of a right triangle, find two oblique angles? Expressed by function

Suppose that the length of the short right angle side is a, the corresponding vertex angle is? 1, the long right angle side is B, and the corresponding vertex angle is? 2
So the length of the hypotenuse is Г A2 + B2
sin?1=a/Гa2+b2 cos?1=b/Гa2+b2 tan?1=a/b
sin?2=b/Гa2+b2 cos?2=a/Гa2+b2 tan?2=b/a

Knowing the two right sides of a right triangle, how to calculate the angle of the remaining two angles?

Let a / b = Tana = cotb. If a / B is a special value, we can calculate a and B angles directly. If a / B is a special value, we can directly calculate the angles a and B. It depends on the calculator or look up the table
That is, a = arctana / B, B = arccota / b
Generally speaking, they are special values. If a = root 3, B = 1, then a / b = root 3. Because tan60 '= root 3, then a = 60', B = 30`

A right triangle knows the length of a hypotenuse and a straight side. How to calculate the length of the third side

Using trigonometric function to solve, sine theorem, a / Sina = B / SINB = C / sinc, simply use Pythagorean theorem, the square of oblique side minus the square of known right angle side length, get the square root of difference, the arithmetic square root is the length of the third side

If two sides of a right triangle are 6 and 8, what is the length of the third side?

2 √ 7 or 10
If 6 is a right angle side and 8 is a hypotenuse, the length of the third side is 2 √ 7
If 6,8 are right angles, the length of the third side is 10
(using Pythagorean theorem)

How to calculate the side length of a right triangle with an angle of 30 ° by using the ratio of 1 to 3 to 2

The length of the right angle to which an angle of 30 ° is opposite is twice the length of the hypotenuse, so 1: (root 3): 2 is the right angle side opposite to 30 ° and the right angle edge opposite to 60 ° is the right angle side opposite to 60 ° if the known edge is a bevel edge, then the right angle edge opposite to 30 ° is 1 / 2 of the known edge, and the right angle edge opposite to 60 ° is (root 3) / 2 of the known edge; if the known edge is the right angle edge opposite to 30 °, the oblique side is 2 times of the known edge, The right angle side to which 60 ° is opposite is (root 3) times of the known edge; if the known edge is the right angle edge opposite to 60 °, the oblique edge is [2 times (root 3)] / 3 times of the known edge, and the right angle edge opposite to 30 ° is (root 3) / 3 times of the known edge

The length of the three sides of a right triangle is 3:4:5. The sum of the two right angles is 140 cm. How many centimeters is the length of the third oblique side

The short right angle side is 140 × 3 ^ (3 + 4) = 60 cm
60÷3×5=100
A: the third oblique side is 100 cm long
