Given the length of the right two sides of a right triangle, what are the angles of the other two angles? The two sides of the right angle are 70cm and 120cm respectively. How many are the other two angles? It's best to take the process

Given the length of the right two sides of a right triangle, what are the angles of the other two angles? The two sides of the right angle are 70cm and 120cm respectively. How many are the other two angles? It's best to take the process

The angle of 70 cm is about 30.26 degrees,
The angle of 120 cm is about 59.74 degrees,

In a right triangle, given its three sides, how to find the two corners except the right angle?

Let the three sides be a, B and C, where C is an oblique edge, and the triangle is a, B, C, where C is a right angle
Then Sina = A / C a = arcsina / C
sinB=b/c B=arcsinb/c

The degree ratio of the three inner angles of a triangle is 2:3:4. How many degrees are the three internal angles of this triangle?

180°×2
2+3+4=40°；
180°×3
2+3+4=60°；
180°×4
2+3+4=80°．
A: the three internal angles are 40 degrees, 60 degrees and 80 degrees respectively

If the degree ratio of the three inner angles of a right triangle is 7:5: X, then the angle to which X is opposite is () degree The circumference of a triangle is 24cm and the length of its three sides is 3:4:5. How many square centimeters is its area?

When x corresponds to a right angle
Then x = 7 + 5 = 12
If 7 corresponds to a right angle
X = 7-5 = 2, 2 / 7 * 90 = 180 / 7 degrees
So it should be 90 degrees or 180 / 7 degrees
Let the edges be 3x, 4x and 5x respectively
Then 3x + 4x + 5x = 24cm
x=2cm
S=1/2*3x*4x=24 cm^2

The ratio of the three inner angles of an isosceles right triangle is ()

The ratio of the three inner angles of an isosceles right triangle is (2:1:1)
Isosceles right triangle: one inner angle = 90 ° and the other two are 45 °
90 ：45 ：45 =2 ：1 ：1

Among the three inner angles of a right triangle, the degree of the smallest angle is one fifth of the degree of the largest angle. What is the smallest angle?

The maximum angle of a right triangle is 90 degrees
The degree of the smallest angle is one fifth of the degree of the largest angle
Then the degree of the minimum angle = 90 ° / 5 = 18 °

There is a right triangle with two right angles of 605. What is the degree of the two angles of this triangle

arctan12 π/4-arctan12

A right triangle with two right sides X and Y. find the degrees of the other two angles

Let the angle of a right angle X be α and the other acute angle be β, then the value of Tan α can be calculated by Tan α = x / y, the angle of α can be calculated from the tangent table in the trigonometric function table, and β value can be obtained by β = 90 ° - α

In a right triangle, 2 times of 1 is 3 times of 2. Find the degrees of ∠ 1 and ∠ 2

Let ∠ 1 be 3x, then ∠ 2 be 2x
The sum of interior angles of triangle is 180 degrees
∴3x+2x+90=180
∴x=18
∴∠1=54°
∠2=36°

What is the degree of the three angles of a right triangle?

Only one is 90 degrees, the other two angles are not limited, as long as the sum is 90 degrees
