Given that a right angle side of a right triangle is 8 and its hypotenuse is 42.3, what is the formula for calculating the length of the other corner

Given that a right angle side of a right triangle is 8 and its hypotenuse is 42.3, what is the formula for calculating the length of the other corner

Formula: A and B are right angle sides, and C are oblique sides. According to Pythagorean theorem, C  2 = a  2 + B  i.e. (42.3  - 8 ) square root is enough

The ratio of two right angles of a right triangle is 16:9, and the hypotenuse is 2.6 meters. Find the length of both sides of the right angle

The square Pythagorean theorem of (9x) 2 + (16x) 2 = 2.6. 9x is the width and 16x is the length
337X²=6.76
X²=0.02
X=0.14

It is known that the area of a right triangle is 108 cm? 2, and the ratio of the length of the two right sides is 2:3 We should use the method of quadratic root

If the shorter right angle side length is x, the longer right angle side length is 3x / 2
x×3x/2÷2＝108
3x²＝432
x²＝144
x＝±12
∵ x＞0
∴ x＝12
Longer right angle side length: 12 × 3 / 2 = 18 cm

A right triangle has a certain area, and the length of its two right angles () A. Positive proportion B. In inverse proportion C. Out of proportion

Because: the base × height = the area of the triangle × 2 (certain), so the area of the right triangle is fixed, and the two right angles are in inverse proportion;
Therefore, B

The difference between the two right sides of a right triangle is 7 cm and the area is 30 cm 2

Let the shorter right angle side be xcm, and the longer one is (x + 7) cm,
One
2x•（x+7）=30，
The results show that: x2 + 7x-60 = 0,
∴（x+12）（x-5）=0，
Ψ x = 5 or x = - 12 (omitted)
5+7=12cm，
52+122=13cm．
The length of the bevel is 13cm

The two right sides of a right triangle are 6cm and 8cm respectively, and the hypotenuse is 10cm A. 2.4 cm B. 4.8 cm C. 6 cm D. 1.2 cm

Let the height on its bevel be x cm,
10x÷2=6×8÷2，
   10x=48，
     x=4.8；
A: its height on the bevel is 4.8 cm;
Therefore, B

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 three sides of a right triangle are 6, 8 and 10 decimeters long, and their area is () square decimeter A. 48 B. 40 C. 30 D. 24

The two right angles are 6 decimeters and 8 decimeters respectively,
The area of the triangle is 6 × 8 △ 2 = 24 (square decimeter)
Therefore, D

If the three sides of a right triangle are 6, 8, x, then what is x? A 6 B 8 c 10 d

C Pythagorean theorem

The two right sides of a right triangle are 6cm and 8cm respectively, and the hypotenuse is 10cm A. 2.4 cm B. 4.8 cm C. 6 cm D. 1.2 cm

Let the height on its bevel be x cm,
10x÷2=6×8÷2，
   10x=48，
     x=4.8；
A: its height on the bevel is 4.8 cm;
Therefore, B
