The height of a right triangle with an oblique angle of 18 ° is 10

The height of a right triangle with an oblique angle of 18 ° is 10


There are two cases
1、 The height a corresponding to the oblique angle is 10
There are
Hypotenuse length C = 10 / sin18 ° = 32.4
Bottom length b = 10 / Tan 18 ° = 30.8
2、 The bevel corresponds to the bevel B of the demand
There are
Hypotenuse length C = 10 / cos 18 ° = 10.5
The length of the bottom edge B = 10 Tan 18 ° = 3.2



In a right triangle, the length of the hypotenuse is 18.688m, and two right angles can be found with an hypotenuse of 28 degrees


Let X be the length of the right angle side and y be the short side
Cosine theorem
Y ^ 2 = x ^ 2 + 18.688 ^ 2 - 2 * y * 18.688 * cos 28 degrees
688 ^ 2 = x ^ 2 + y ^ 2 - 2 * x * y * cos 90 degrees
Do the rest by yourself
I did it myself,
x=18,y=5



Given that the height of a right triangle is 1000 and the included angle is 30 degrees, how to find another right side?


The height of a right triangle is a right side with an angle of 30 degrees, which is not accurate because the angle refers to the angle between two sides
I understand it is the neighborhood of 1000 high
The other right angle side = 1000 * Tan 30 ° = 1000 * √ 3 / 3



The three angles of a right triangle are 30 degrees, 60 degrees and 90 degrees respectively. What is the quantitative relationship between the corresponding sides of a 30 degree angle and the corresponding sides of a 90 degree angle?


The ratio of 30 degree edge to 90 degree edge is 1:2



What is the ratio of three sides of a right triangle with 30 degree angle


From short to long, 1: radical, 3: 2



What are the ratios of the opposite sides of right triangles of 30, 60 and 90 degrees?
Such as the title


1: Root 3:2



The proportion of the three sides of a 30 degree right triangle


Right angle side: bevel side: right angle side
1: 2: radical 3



The proportion of the three sides of a triangle with 30 degrees, 60 degrees and 90 degrees


Let a, B and C be the three sides corresponding to 30 degrees, 60 degrees and 90 degrees respectively
Then a: B: C = 1: radical 3:2



What is the ratio of the three sides in a right triangle with two angles of 60 and 30 degrees?


The ratio of three sides = sin30: sin60: sin90 = 1: 3:2 under the root sign



A right triangle, one of its acute angles is 28 degrees, the other is how many degrees?
Distributed, comprehensive, distributed to have a subtitle


The sum of the internal angles of a triangle is 180 degrees, a right angle is 90 degrees, and one of the acute angles is 28 degrees. To find another internal angle, 180-90-28 degrees are used
180 degrees - 90 degrees - 28 degrees
=90-28 degrees
=62 degrees
A: the other acute angle is 62 degrees
