In a right triangle, the lengths of two right angles are known: 12 meters and 3.6 meters respectively. The length of the hypotenuse and the degree of the minimum acute angle are calculated

In a right triangle, the lengths of two right angles are known: 12 meters and 3.6 meters respectively. The length of the hypotenuse and the degree of the minimum acute angle are calculated

Pythagorean theorem, root inside the square of 12 plus 3.6 square, you can work out, as for the minimum angle degree, with sin, Tan, cos what can be, click the calculator, very fast!

There is a right triangle with an angle of 30 degrees. What is the ratio between the length of the right side corresponding to an angle of 30 degrees and the length of the right side corresponding to an angle of 60 degrees?

In a right triangle, the right side of 60 ° is equal to three times the root of the right side of 30 °

In a right triangle, there is an angle of 30 degrees, two right angled sides and a diagonal line. Or what is the formula that one line can find out the other line

The short right angle side is 1 to root and the long right angle side is 3 to 2
According to the number of copies

If the angle is one to two, the angle three equals one to two to four, and the angle one plus the angle two plus the angle three equals 140 degrees, find the degree of the angle one, the angle two and the angle three

∠1：∠2：∠3=1：2：4
Then ∠ 2 = 2 ∠ 1
∠3=4∠1
It is known that ∠ 1 + 2 + 3 = 140
∴∠1+2∠1+4∠1=140
7∠1=140
∠1=20
∴∠2=40
∠3=80

The right sides of a right triangle are 3 and 13 respectively to find the degree of two acute angles

Use the calculator to shift Tan 13 / 3 = 77 ° and the other angle is 13 °

It is known that the right sides of a right triangle are 11 and 4, and the other is 11 and 13. Find the degree of two triangles

tanA=4/11A≈19.98°B=90°-A=70.02°tanA=11/13A≈40.24°B=90°-A=49.76°

In a right triangle, the degree of angle 2 is 80% of the degree of angle 1. What are angle 2 and angle 1

Angle 1 + angle 2 = 90 degrees, angle 2 = 80% angle 1,
So: angle 1 + 80% angle 1 = 90,
180% angle 1 = 90,
So: angle 1 = 50 degrees, angle 2 = 40 degrees

In a right triangle, the degree ratio of the largest angle to the smallest angle is 5:1, so what is the degree difference between them?
Thank you. It's urgent

What is a right triangle? It is a triangle in which one angle is a right angle, and the largest angle is a right angle, so the ratio of the largest angle to the smallest angle is 5:1 = 90:x
So x = 18 degrees
90-18=72°
Their degrees are 72 degrees apart

As shown in the figure, in the triangle ABC sheet, e is the point on ad, D is the point on BF, f is the point on CE, ∠ 1 = ∠ 2 = ∠ 3, ∠ BAC = 80 °, calculate the degree of ∠ def

∵∠DEF＋∠AEC＝180,∠3＋∠EAC＋∠AEC＝180
∴∠DEF＝∠3＋∠EAC
∵∠1＝∠3
∴∠DEF＝∠1＋∠EAC
And ∵ BAC = 1 ＋ EAC = 80 °
∴∠DEF＝∠BAC＝80°

In △ ABC and △ def, are the triangles ∠ a = 70 °, B = 60 ° and E = 50 ° similar? Why?
There should be a complete process, wrong number, is ∠ a = ∠ d = 70 degree

Similar
According to the theorem of the sum of internal angles of triangles, we can get ∠ C = 180-70-60 = 50 degree
∴∠E=∠C
∵∠A=∠D=70°
∴△ABC∽△DFE
