The angle between the hypotenuse and the base of a right triangle is 30 degrees. The length of the hypotenuse is 1.7 meters. How to find the length of the bottom edge?

When the angle of a right triangle is 30 degrees, the length of the bottom edge is equal to half of the hypotenuse

Known height 40 cm, oblique angle 30 degrees

40 times sin 30 degrees is 80 cm

Given that the length of the straight side of a right triangle is 120cm and the angle of the oblique angle is 45 °, find the length of the hypotenuse

It's easy. One angle is 45, and the other is 45. Isn't this isosceles right triangle? You should learn the Pythagorean theorem? The sum of the squares of the two right angles is equal to the square of the hypotenuse. You can just root 28800

Known right triangle height, 3.5 meters, angle 12 degrees, length, urgent

Sin12 = 3.5/bevel
Bevel = 3.5 / sin12 = 16.8341

The hypotenuse of a right triangle is 4 larger than that of a right triangle, and the other side is 8 RT、

Because the hypotenuse side is 4 larger than a right angle side, let this right angle side be x, so the oblique side is x + 4. And because the length of the other right angle side is 8. Therefore, according to the Pythagorean theorem: "the sum of the squares of two right angle sides is equal to the square of the sum of X + 4"

Given that the length of two right triangle is 3M 3.7m, calculate the length of hypotenuse What's the simplest algorithm you've ever learned before（

According to the Pythagorean theorem, it is known that it is a right triangle, so 3 ^ 2 × 3.7 ^ 2 = 22.69 ^ 2, so the hypotenuse is the root sign 22.69

The hypotenuse of a right triangle is 2m, and the angle between the base and the hypotenuse is 5 degrees?

Let three sides be a, B, C, C = 2
Then a = 2 * sin 5 is about 2 * 0.087 = 0.174
B = 2 * cos 5 is about 2 * 0.996 = 1.992

Known a right triangle, the height is 1.3m, the angle between the base and the hypotenuse is 50 degrees, how to calculate the length of the base and hypotenuse

Height / bevel = sin50
Height / bottom edge = tan50

How big is a mu of land, several meters in length and several meters in width, I only know how long a meter is How big is a mu of land, a few meters in length and a few meters in width. I only know how long a meter is. I don't know how long and how wide a mu is. There are also square meters. How long and how wide are 10 square meters? One mu is equal to several square meters. Who can answer me? Thank you for your support

One mu of land is 666.67 square meters. If it is square, the side length is about 25.82 meters, and 10 square meters is 10 meters * 1 meter!

Knowing that the waist of an isosceles right triangle is one meter, how to find the length of the other side?

Use trigonometric function to find the bottom edge
Hypotenuse = right angle side / sin45 ° = 1 / (1 / 2 root 2) = root 2

The angle between the hypotenuse and the base of a right triangle is 30 degrees. The length of the hypotenuse is 1.7 meters. How to find the length of the bottom edge?
