The sum of the two right sides of a right triangle is 12 cm. The length of the hypotenuse is 10 cm. What is the area of this right triangle
x+y=12
Square x ^ 2 + 2XY + y ^ 2 = 144
From the bevel side is 10: x ^ 2 + y ^ 2 = 100
Subtract 2XY = 44
So area: XY / 2 = 11
The area is 11
A right triangle, oblique side length of 20 cm, two right angle side length difference of 4 cm, calculate the area of right triangle Please draw a picture and write out the calculation process. Use the cut and fill translation method to solve the problem
Let two right angles be x, x + 4 respectively
x^2+(x+4)^2=20^2
2x^2+8x+16=400
x^2+4x-192=0
(x+16)(x-12)=0
x=12
x+4=16
Area = 1 / 2 * 12 * 16 = 96 square centimeter
One right side of a right triangle is one-third of the other. The length of the hypotenuse is 10 and the area is?
If the short right angle side is x, then the long right angle side is 3x, then the square of x plus the square of 3x is the hypotenuse square
One right side of a right triangle is one of the other 3, if the length of the bevel is 10, then its area is () A. 10 B. 15 C. 20 D. 30
One right side of a right triangle is one of the other
3. Let one side be a and the other side 3a,
According to Pythagorean theorem, the equation A2 + (3a) 2 = 100 is obtained,
A=
10, then the other corner is 3
10，
Then the area is: 1
2 x
10×3
10=15．
Therefore, B
A right triangle. The length of the side opposite the right angle is 10 cm, and the other two sides are 8 cm and 6 cm respectively______ Centimeter
8 × 6 △ 2 = 24 (square centimeter),
24 × 2 △ 10 = 4.8 (CM);
A: the height on the opposite side of the right angle is 4.8 cm
Therefore, the answer is: 4
A right triangle. The length of the side opposite the right angle is 10 cm, and the other two sides are 8 cm and 6 cm respectively______ Centimeter
8 × 6 △ 2 = 24 (square centimeter),
24 × 2 △ 10 = 4.8 (CM);
A: the height on the opposite side of the right angle is 4.8 cm
Therefore, the answer is: 4
A right triangle, two right sides are 10 cm, 8 cm, its area is () square centimeter
S = 10 × 8 △ 2 = 40 square centimeter
The length of three sides of a right triangle is 6cm, 10cm and 8cm respectively. The area of this right triangle is______ cm2．
6 × 8 △ 2 = 24 (square centimeter);
A: the area of this right triangle is 24 square centimeters
So the answer is: 24
The length of the non right angle side of an isosceles right triangle is 10cm. How many square centimeters is its area?
The area is: 10 * (10 / 2) / 2 = 25 (square centimeter)
The area of a right triangle is 27 square centimeters, one right angle side is 9 centimeters, and how many centimeters is the other right angle side
Let the other right angle side be x cm
1/2（9×x）=27
X=6
A: the other right angle side is 6cm
