The ratio of acute angles of a right angle is 4:5

The ratio of acute angles of a right angle is 4:5

If a right angle is 90 degrees and the sum of acute angles is 10 degrees, then 90 * 5 / 9 = 50 degrees

If the difference between the bright and acute angles of a right triangle is 12 degrees, the degree of the larger acute angle is ()

Smaller one acute angle X degree
2x+12=90
2x=78
x=39
One sharp angle = 12 x = 51

If the degree of an acute angle of a right triangle is a, the opposite side length of the acute angle is x, and the length of the adjacent right angle side is 1 If the length of a right angle SA is a right angle, how is there a relationship between the length of the right angle A and the length of a right angle?

From the meaning of the title,
tanA=x
sinA=x/ √(1+x^2)
cosA=1/ √(1+x^2)
When x increases from 0 to 0, Tana and Sina increase, and cosa decreases

If ∠ A is an acute angle and Sina = cosa, then the degree of ∠ A is______ Degree

∵ A is an acute angle, and Sina = cosa,
∴tanA=1，
∴∠A=45°．

The ratio of the two acute angles of a right triangle is 2:1. How many degrees are these two acute angles?

The sum of the two acute angles of a right triangle = 90 °,
90°*2/(2+1)=60°；
90°-60°=30°；
These two acute angles are 60 degrees and 30 degrees respectively

The degree ratio of two acute angles of a right triangle is 2:7______ Degree sum______ Degree

Because the sum of the inner angles of a triangle is 180 ° and one of the right triangles is 90 °,
So the sum of the two acute angles of a right triangle is 90 degrees,
So these two acute angles are 90 ° x 2
2+7=20°；
90°×7
2+7=70°；
A: the degrees of the two acute angles of this triangle are 20 ° and 70 ° respectively
So the answer is: 20, 70

In a right triangle, the ratio of two acute angles is 3:2______ Degree and______ °．

90°×3
3+2=54°，
90°-54°=36°；
So the answer is: 54, 36

For a right triangle, the degree ratio of two acute angles is 2:3. The two acute angles are () and () degrees respectively. Fill in the blanks!

It's 36 degrees and 54 degrees, respectively

In a right triangle, the ratio of the degree of a right angle to that of an acute angle is 3:2. What is the degree of the other acute angle?

30°

Two acute angles of a right triangle, angle 1 and angle 2, the degree of angle 2 is 1 / 2 of angle 1, angle 1 is（

Angle 1 + angle 2 = 90 degrees
Angle 1 = 2 * angle 2
3 * angle 2 = 90 degrees
Angle 2 = 30 degrees
Angle 1 = 60 degrees
