The degrees inside a triangle _always_ add up to 180. Do you need proof?

How many triangles exist with the given side lengths 30 degrees 65 degrees 85 degrees?

To determine how many triangles can be formed with the given angles of 30 degrees, 65 degrees, and 85 degrees, we can use the fact that the sum of the angles in a triangle must equal 180 degrees. Since these angles do indeed sum up to 180 degrees, exactly one triangle can be formed with these angles. Thus, there is only one triangle with the specified angles.


On the surface of a sphere the sum of the angles of a triangle equals 180 degrees?

That's correct! On the surface of a sphere, the sum of the angles of a triangle can be less than 180 degrees or more than 180 degrees depending on the size of the triangle and the curvature of the sphere. If the triangle is small enough compared to the size of the sphere, the sum will be approximately 180 degrees, but this is not always the case.


What is the value of cos 30 degrees?

The value of cos 30 degrees is (\frac{\sqrt{3}}{2}). This is a commonly used value in trigonometry, derived from the properties of a 30-60-90 triangle. In this triangle, the ratio of the adjacent side to the hypotenuse corresponds to the cosine of 30 degrees.


Isosceles triangles equal 180 degrees?

The total sum of angles of a triangle is 180, so only one angle of a triangle can be 90 ( making it a right angled triangle).However the sum of two angles of a triangle can be equal to 90, once again making it a right angled triangle.it is possible that two angle can be equal to 180-The acute angles of a right triangle are complementary.SUPPOSE ABC IS A TRIANGLE, where C = 90, thenA+B+90 = 180,A+B = 180-90or A+B = 90,or A = 90-Bso it's possible.


What is at 30 degrees 31 minutes north 75 degrees 12 minutes west?

Read percy Jackson and the sea of monsters. Or the answer is THE SEA OF MONSTERS. In other words THE BERMUDA TRIANGLE. That's what mortals call it.

The sum of the interior angles of a triangle is?

The sum of the interior angles of a triangle is 180 degrees. This is because one angle of a triangle is 60 degrees.


What is a triangle measuring 55 degrees 45 degrees and 80 degrees?

A triangle with angles measuring 55 degrees, 45 degrees, and 80 degrees is a valid triangle because the sum of its angles equals 180 degrees. This triangle is classified as an acute triangle since all its angles are less than 90 degrees. Additionally, it does not have any sides of equal length, making it a scalene triangle.


What is the total degrees of a triangle in algebra?

In total, a triangle has 180 degrees.
