How many hypotenuse sides of the right triangle are the sum of the right angles? I know: do not need to deal with 6, as long as consider? +? = 7, using Pythagorean theorem calculation, you can know

How many hypotenuse sides of the right triangle are the sum of the right angles? I know: do not need to deal with 6, as long as consider? +? = 7, using Pythagorean theorem calculation, you can know

Let the two right angles be a, B and the hypotenuse be c
Then a + B = 7, AB / 2 = 6
The solution is a = 4, B = 3 or a = 3, B = 4
c=√(a^2+b^2)=√(3^2+4^2)=5

In the right triangle ABC, ∠ C = 90 ° the degree of obtuse angle ∠ ADB formed by the intersection of bisectors of two acute angles How much is it

135 degrees

In a right triangle, the obtuse angle formed by the intersection of bisectors of two acute angles is?

135 degrees (180 degrees - 1 / 2 times two acute angles 90 degrees)

For a right triangle, the angle ratio of two acute angles is 3:2, and the degrees of these two acute angles are () and () degrees respectively

Linda,
The degrees of the two acute angles are:
90 × 3 / (3 + 2) = 54 (degree)
90 × 2 / (3 + 2) = 36 (degree)

The ratio of the degree of two acute angles of a right triangle is 2 to 3. The two acute angles are () ° and () ° This problem belongs to the ratio and ratio in the mathematics blank filling problem of volume one of six years

90/(2+3)=18
18*2=36
18*3=54
These two acute angles are (36) ° and (54) °

For a right triangle, the ratio of its two acute angles is 2:3, and the two angles are several degrees and several degrees respectively

90 △ (2 + 3) × 2 = 36 degrees
90 - 36 = 54 degrees

If the ratio of the three inner angles of a triangle is 2:3:4, then the triangle is () A. Right triangle B. Acute triangle C. Obtuse triangle D. Equilateral triangle

∵ the ratio of the three angles of the triangle is 2:3:4,
The three internal angles are 180 ° x 2
9=40°，180°×3
9=60°，180°×4
9=80°．
So the triangle is an acute triangle
Therefore, B

For an isosceles triangle, the ratio of the degrees of the three inner angles is 1:1:2, and this triangle is (). A right triangle B acute angle triangle C obtuse angle triangle

Divide 180 degrees by (1 + 1 + 2) to get 45 degrees for each angle. Multiply 45 degrees by 2 to get 90 degrees

If the ratio of the inner angles of a triangle is 2:7:4, then the triangle is a. right triangle B. acute angle triangle C. obtuse angle three If the ratio of the inner angles of a triangle is 2:7:4, then the triangle is A. Right triangle B. Acute triangle C. Obtuse triangle D. Not sure

Let the degrees of the three inner angles be 2x, 7x and 4x respectively
Then 2x + 7x + 4x = 180 degrees
13x=180°
Then x = 180 / 13
So ∠ a = 260 ° / 13
∠B=1260°/13
∠C=720/13
Therefore, the triangle is an obtuse angle triangle

How many degrees is the obtuse angle between the bisector of two acute angles of a right triangle

If the sum of the two acute angles of a right triangle is 90 degrees, the sum of the two acute angles is 45 degrees. Then the obtuse angle between the bisectors of the two acute angles is 180-45 = 135 degrees
