To know the three sides of a right triangle, how to find the degrees of the three angles

Cosine theorem ah ~ in any △ ABC, the side to which ∠ C is opposite is C, the side opposite to ∠ B is B, and the square of one side is equal to the sum of the squares of the other two sides minus the cosine product of the angle between the two sides and them, COSC = (a? + B? - C?) / 2Ab CoSb = (a? + C? - B?) / 2AC cosa = (C? + B? - a?) 2BC

In a right triangle, the degrees of the three angles are 30.60.90. The two right sides are 3 and 4 respectively. What is the hypotenuse?

This is an impossible thing. The angle determines the ratio between the two right angles and the hypotenuse. It is impossible for a triangle with three angles of 30, 60 and 90 to have the right angles of 3 and 4
Therefore, this is a wrong proposition

In a right triangle, the degrees of the three angles are 30.60.90 and the hypotenuse is 6

The method of calculating the side length of a right triangle is Pythagorean theorem
Where a and B are right angles and C is bevel
The formula of Pythagorean theorem is "the square of C minus the square of a / B to get the answer
In this case, the answer is not ^ 2-2
√ 27 = √ 3 × √ 9 (the value of root 9 is 3)
The final answer is 3 ×√ 3 = 3 √ 3

The right angles of a right triangle are 1.5 and 8. Find the degrees of the other side and the other two angles (formula)

Pythagorean theorem: 22 2
a +b =c
A -- right angle side 1
B -- right angle side 2
C - beveled edge
2 2 2
Bevel = 1.5 + 8
tanA=a\b
cotA=b\a
Can you use a calculator? Just bring it in

A right triangle has a right angle side of 25 and a right angle side of 13.4. Find the degree of an angle

Find a calculator, calculate 13.4/25, and then press the anti tangent Tan to get an angle of 28.19

How to calculate the other side of a right triangle given an acute angle degree and length of one side?

First of all, you have to determine the position of the edge and the angle
Is it a hypotenuse or a right angle? Is it the opposite or adjacent edge of a known acute angle
Any size, using trigonometric function calculation can be
If it is special, there are Pythagorean number, special angle, triangle proportion and so on
For example:
A 30 degree right angle is half the length of the hypotenuse, and the long right angle is three times the root of the short right angle

In a right triangle, the ratio of an acute angle to a right angle degree is 2:3, this acute angle is () degree, and the other acute angle is () degree 2. The ratio of number a to number B is 5:6, number a is 10, number B is (). 3, the average number of two numbers is 12, the ratio of two numbers is 3:5, number a is () and number B is ()

1. In a right triangle, the ratio of an acute angle to a right angle degree is 2:3, the acute angle is (60) degrees, and the other acute angle is (30) degrees
The ratio of a and B is 5:6, number a is 10, number B is (12)
3. The average of the two numbers is 12, the ratio of them is 3:5, the number of a is (9), the number of B is (15)

In a right triangle, the degree of one acute angle is twice that of the other. How many degrees are the two acute angles?

If one of the acute angles is x, then the other is 2x. Because in a right triangle, 90 + 3x = 180 and x = 30 °, then one of the acute angles is 30 ° and the other is 60 °

Mathematics problem a right triangle, the degree ratio of its two acute angles is 4:1, how many degrees are the two acute angles different

The degree of the remaining two acute angles: 180-90 = 90 (degrees)
Then use the method of proportional distribution 4 + 1 = 5
90 × 4 / 5 = 72 (degree)
90 × 1 / 5 = 18 (degree)
72-18 = 54 (degrees)
