If the two right sides of a right triangle are 5 and 12, and the hypotenuse is 13, what is the height of the hypotenuse? This is a question to fill in the blanks. Just tell me the big problem

60/13

The ratio of the two right angles of a right angle △ is 5:12, and the length of the hypotenuse is 26cm? The third problem in junior high school is solved by one variable quadratic equation

Let the two right angles be 5x.12x
(5x)^2+(12x)^2=26^2
169x^2=676
X=2
So the area is: 1 / 2 * 5x * 12x = 1 / 2 * 5 * 2 * 12 * 2 = 120

The perimeter of a right triangle is 12 cm and the length of its hypotenuse is 5 cm

If one right angle side is xcm, then the other right angle side is (7-x) cm
x2+（7-x）2=52
X = 3 or 4
Then the area of the right triangle is: 1
2×3×4=6cm2．
A: the area of a right triangle is 6cm2

For a right triangle, the side lengths of the two straight legs are 5 and 12 respectively

According to the Pythagorean theorem, the square of the length of the hypotenuse is equal to a 2 + B 2, i.e. 5 2 + 12 2. Therefore, the length of the hypotenuse is 13. Because the area of the triangle is 12 * 5 / 2, the area of the triangle is 30, so the height of the hypotenuse * the hypotenuse = 30 * 2 = 60, so the height and length of the hypotenuse is 60 / 13

If the lengths of the two right sides of a right triangle are 5 and 12, then the height on the hypotenuse is______ .

In a right triangle, two right sides are known to be 5, 12,
The length of the oblique side is
52+122=13，
According to the area method, the area of a right triangle can be evaluated according to the two right angles, the hypotenuse and the height on the hypotenuse,
Then the product of two right angles = the length of the oblique side × the length of the high line on the inclined side,
Length of high line on bevel = 5 × 12
13=60
13，
So the answer is: 60

How to find the side length of a right triangle We know that the hypotenuse AB is 12cm, the opposite side BC of a is x, and the degree of a is 55 ° C is 90 ° B is 35 ° we only know that this is about the sine cosine problem, but we can't do it. We don't need to do anything we don't understand

First draw the right triangle according to the meaning of the title, sin55 ° = x / 12, x = 12sin55 ° = 9.83

A right triangle, a right angle side 8 meters long, included angle 11 degrees, find another right angle side

Using sine formula: let the right angle side to be solved be X. then x / sin11 = 8 / sin78 or X / sin78 = 8 / sin11

Let a right triangle have an acute angle of 42 degrees, and the length of one right angle side is 9cm. Find the length of the other two sides?

1. The length of the right angle side is 9cm, and the angle is 42 degrees
Then the other right angle side = 9 * tan42 degrees
Hypotenuse = 9 * √ (1 + Tan ^ 242 °)
2. The length of the right angle side is not 9cm, and the opposite angle is 42 degrees
Then the other right angle side = 9 / Tan 42 degrees
Bevel = 9 * √ (1 + 1 / Tan ^ 242 °)

Right triangle, three angles are 30, 60, 90, 60 degrees, the opposite side is 500, how to calculate the length of two sides

Three strands and four metaphysics
A right angle is twice the edge to which 30 degrees are opposite. Let the short right angle side be x and the hypotenuse side be 2x
500*500+X^2=4x^2
Radical 3 * x = 500
X = (500 * root 3) / 3
The hypotenuse is 2 * (500 * root 3) / 3

If the length of the adjacent side of a 60 degree angle in a right triangle is 1, then the length of the opposite side is - and the length of the oblique side is -. Therefore, sin 60 degree = -, cos 60 degree = -

According to the order. The opposite side is radical 3, and the hypotenuse is 2
Sin60 = radical 3 / 2 cos60 = 1 / 2

If the two right sides of a right triangle are 5 and 12, and the hypotenuse is 13, what is the height of the hypotenuse? This is a question to fill in the blanks. Just tell me the big problem
