How do you calculate the missing degree of a triangle?

Anonymous

∙ 12y ago

Updated: 11/5/2022

The sum of all the angles in a triangle equals 180o. To find the missing angle, subtract the sum of the two known angles from 180o.

Example

Two angles of a triangle are 35o and 62o. What is the third angle?

Solution

180o - (35o + 62o) =

180o - 97o = 83o

Can an equilateral triangle have a total of 120 degrees?

no because an equilateral triangle is a total of 180 degrees not 120. but if you need to find the missing angle or missing degree then yes!

How do you calculate sides of triangle if you know the height and base?

If the triangle is right-angled then you should be able to use Pytharoras Theorem to calculate the missing side otherwise you need an angle to be able to use trigonometry

How do you calculate the missing length of a triangle?

It depends on what other information you have. Knowing the lengths of two sides of a triangle is not enough to calculate the third. You need to have some further information: and angle, the area, the length of an altitude or a median.

If one side of right triangle is 21 what are the other twos measures?

There is not enough information to calculate the two missing sides.

How do you find the area of a 45- 45 -90 degree triangle?

Depends on the length of the sides ! The simple formula to calculate the area of a triangle is half the base times the height.

What is the is the missing degree on a angle that one angle is 22 degrees and the other is 51 degrees?

I will assume that this is referring to a triangle. The angles of a triangle add up to 180 degrees. Let the missing angle = a then a + 22 degrees + 51 degrees = 180 degrees a = 107 degrees
