In a right triangle, if one acute angle is twice the other, then the degree of these two acute angles is______ .

If one angle is x, then the other is 2x,
According to the meaning of the title, x + 2x = 90 °,
X = 30 ° is obtained,
2x=60°．
So these two acute angles are 30 ° and 60 ° respectively
So the answer is: 30 ° and 60 ° respectively

In a right triangle, the degree of one acute angle is twice that of the other. How many degrees are the two? 3. The degree of the top angle of an isosceles triangle is four times that of the base angle. How many degrees are the top angle and base angle of this isosceles triangle, and what triangle is it?

180-90=90
90/（1+2）=30
90-30=60

It is known that the short side of a right triangle is 1.65 and the hypotenuse is 25.6. The diagonal of the hypotenuse is the degree of the third pass and two angles of the right angle

Using Pythagorean theorem, the length of the third side can be calculated as 25.55
The two angles are 3.7 ° and 86.3 ° respectively

Known a right triangle, a right angle side is 5 cm, the other is 10 cm, the degree of two angles. Thank you very much

In RT △ ABC, ∠ C = 90 °,
((opposite sides of ∠ a, ∠ B, ∠ C are a, B, C.)
And a = 5 cm, B = 10 cm
Then Tan a = A / b = 1 / 2,
tan B =b/a =2.
Look up the table and get a=
B=
= = = = = = = = =

The high bisecting hypotenuse on the hypotenuse of a right triangle. The degree of an acute angle of this right triangle is

Three in one
isosceles right triangle
45°

In a triangle, ∠ 1 is twice of ∠ 2, and ∠ 2 is 20 degrees larger than ∠ 3. Find the degrees of the three angles of this triangle. What triangle is this?

According to the meaning of the title, ∠ 1 = 2 ∠ 2; ∠ 3 = ∠ 2-20 degrees
According to the fact that the sum of the inner angles of the triangle is 180 degrees, 2 ∠ 2 + ∠ 2-20 degrees = 180 degrees
The solution is ∠ 2 = 50 degrees
The results show that ∠ 1 = 100 degrees, ∠ 3 = 30 degrees
The triangle is obtuse angle triangle

The degree ratio of the three inner angles of a triangle is 2:3:5______ (judge right or wrong)

5+3+2=10，
Maximum angle: 180 °× 5
10 = 90 degrees, so this triangle is a right triangle
So the answer is: √

Find the degree sum of the angles between the bisector of two acute angles and the hypotenuse of a right triangle

Shit! It's so simple that I dare to ask!
Assuming that the two acute angles are a and B respectively, then:
Angle a the angle between bisector and bevel edge a / 2;
Angle B the angle between bisector and bevel B / 2
Therefore, the sum of the angles between the bisectors and the hypotenuse is (a + b) / 2;
Because a + B = 90 degrees;
So (a + b) / 2 = 45 degrees

A right triangle with sides 3 and 30. Find the length of the other side and the degree of one of its angles

According to the Pythagorean theorem, if both sides are right angles, the length of the other side is 30 ^ 2 + 3 ^ 2 = 909 under the root = 101 under the root, and the angle a = arcsin (3 / 909 under the root) = 5.71 degrees
If one is a hypotenuse, the length of the other side is 30 ^ 2-3 ^ 2 = 891 = 9 times 11, and the angle a = arcsin (3 / 30) = 5.74 degrees

A right triangle knows that one side is 13 and the other side is 16. Can we find the degrees of the other two angles? I forgot

After the length and angle (90 degrees) of both sides are determined, the triangle is determined
So, the other two angles are also determined
The degree of one of the angles is arctan 13 / 16 and the other arccot16 / 13
If the angle between the two sides is not 90 degrees,
So, the degree of one of the angles is arcsin13 / 16, and the other is 90-arcsin13 / 16
Right? I'm sorry

In a right triangle, if one acute angle is twice the other, then the degree of these two acute angles is______ .
