If the ratio of the two right sides of a right triangle is 3:4 and the length of the hypotenuse is 25, then the height of the hypotenuse is______ .

Let the length of two right angles be 3x and 4x, and according to Pythagorean theorem, we know that the length of oblique side is 5x
And the slant side length is 25, so x = 5,
That is, the two right angles are 15 and 20,
If the height on the hypotenuse is h, then 15 × 20 = 25h,
The solution is h = 12,
So the answer is 12

(1 / 2) in a right triangle, if the two right sides are 3 and 4 respectively, then the ratio of the height of the hypotenuse and the hypotenuse of the triangle is () a, 25 of 12 (1 / 2) in a right triangle, if the two right sides are 3 and 4 respectively, the ratio of the hypotenuse of the triangle to the height of the hypotenuse is () A. 25 B of 12, 5 of 12

Since the multiple choice question does not need the process, drop to choose a high certainly does not have the slant side long ha to exclude B

If the ratio of the two right sides of a right triangle is 3:4 and the length of the hypotenuse is 25, then the height of the hypotenuse is______ .

The length of three sides of a right triangle is 20 cm, 16 cm and 10 cm respectively, and the height on the longest side is () cm

(16×10÷2)÷(20÷2)
=80÷10
=8 cm

The height of the hypotenuse of a right triangle is () cm A. 4.8 B. 8 C. 9.6 D. 10

Let the height of the hypotenuse be x cm
20×x÷2=12×16÷2，
     10x=96，
       x=96÷10，
       x=9.6；
A: the height on the bevel is 9.6cm
Therefore, C

The two right angles of a right triangle are 12cm and 16cm respectively. The height of the hypotenuse is 9.6cm. The circumference of this right triangle is______ Centimeter

12×16÷2×2÷9.6，
=192÷9.6，
=20 (CM);
12+16+20，
=28+20，
=48 (CM);
A: the circumference of this right triangle is 48 cm
So the answer is: 48

The circumference of a right triangle is 12 cm, and the length of two right sides is 3 cm and 4 cm respectively

12-3-4=5
3×4÷2=6
5 × high △ 2 = 6
Height = 2.4

Math problem: cut a right triangle scarf with a cloth 20 decimeters long and 16.8 decimeters wide It's not over. There's more A piece of cloth with a length of 20 decimeters and a width of 16.8 decimeters is used to cut into a right triangle scarf. The length of the right angle side is 3 and 4 decimeters, and the length of the slant side is 5 decimeters. How many pieces of right triangle scarf can be cut out without splicing? Who is right???

Analysis: the title can be converted into a piece of cloth with a length of 20 decimeters and a width of 16.8 decimeters. What is the maximum number of rectangles with a length of 3 decimeters and a width of 4 decimeters? Because a right triangle with a right angle side length of 3 decimeters and a width of 4 decimeters and an oblique side length of 5 minutes can be assembled into a long square?
20 ÷ 3 = 6.666, rounded to 6
16.8 ÷ 4 = 4.2, 4 can be cut 6 × 4 = 24 rectangles, and the number of triangles trimmed is 24 × 2 = 48
The number of triangles that can be trimmed is 5 × 5 × 2 = 50
You can cut 50 such right triangle scarves

If the ratio of the two right sides of a right triangle is 3:4 and the length of the hypotenuse is 25, then the height of the hypotenuse is______ .
