The length of three sides of a right triangle is three consecutive integers? Solving practical problems with equations

The length of three sides of a right triangle is three consecutive integers? Solving practical problems with equations

Let me tell you the answer is 3, 4, 5, the most basic Pythagorean theorem
If the shortest side is a, then the two sides are a + 1 and a + 2 respectively
a^2+(a+1)^2=(a+2)^2
a^2-2a+1=4
A1 = 3, A2 = - 1 discard
So: a = 3, a + 1 = 4, a + 2 = 5

All three sides of a right triangle are integers

Are you looking for a possible side length?
So A lot!
For example:
3、4、5；
5、12、13；
6、8、10；
7、24、25；
8、15、17；
10、24、26；
12、35、37；
……

The ratio of the length of the three sides of a right triangle is 3:4:5. The sum of the lengths of the two right sides is 140 cm. Find the length of the third side of the triangle

The hypotenuse must be 5. In a right triangle, the hypotenuse is the longest
First, find one part, 140 / (3 + 4) = 20
The bevel is 20 * 5 = 100

An isosceles right triangle, its area is 72 square decimeters, its two right angles side length is_____ .

An isosceles right triangle with an area of 72 square decimeters,
Its two right angles are 6 √ 2 decimeters in length

For an isosceles right triangle, the sum of the two right sides is 8.8 decimeters. What is its area?

For example, in the isosceles right triangle, the sum of the two right sides is 8.8 decimeters, 8.8 / 2 = 4.4 decimeters, so the right angle side = 4.4 decimeters, the height = 4.4 decimeters, the area = the base times the height, that is, 4.4 × 4.4 = 19.36 (square decimeters),

The area of a right triangle is 90 square decimeters. One right angle side is 9 square decimeters. What is the other right angle side What is the area?

The area of a right triangle is 90 square decimeters, and a right angle side is 9 square decimeters,
The other right angle side is 90 × 2 △ 9 = 20 decimeters
If you add it to a rectangle, the area will be 9 × 20 = 180 square decimeters

The area of a right triangle is 48 square decimeters. One of its right angles is 8 decimeters and the other is ()

(48 × 2) × 8 = 12

An isosceles right triangle has a right angle side length of 12 decimeters and an area of? Square decimeters

12×12÷2=72

The area of a right triangle is 18 square centimeters. The length of one right angle side is 9 centimeters. How many centimeters is the length of the other right angle side?

“lijiamin223214”：
18cm²÷9cm×2＝4cm
A: the other right angle side is 4cm,
Checking calculation: 4cm × 9cm △ 2 = 18cm
The check is correct. Good bye

The area of a right triangle is 126 square centimeters. The length of one right angle side is 18 centimeters. How many centimeters is the length of the other right angle side go Using equations

Let the area be s, the right angle sides are a and B respectively, and a = 18, find B
From S = AB / 2, B = 2S / a = 2 * 126 / 18 = 14cm
