Sum of all the angles in the triangle has to be 180 degrees.

Let's mark the largest angle as x.

Then, smallest angle will be 0.5x and the middle one x-25.

x + 0.5x +x - 25 = 180, which is after simplyfying:

2.5x = 205

x = 82 degrees -> the largest angle,

x-25 = 57 degrees -> middle one,

0.5x = 41 degrees -> the smallest angle.

Largest = 86, Smallest 26


What is the term for data in order form smallest to largest?

From smallest to largest is known as putting data in ascending order.


What type of angle is the largest in a triangle?

the obtuse angle is the largest angle in a triangle. It spreads from 91 to 179 on a protractor


In a triangle the measure of the largest angle is 3 times the measure of the smallest angle The measure of the remaining angle is twice the measure of the smallest angle Measure of the largest angle?

Cryptogram said 45, but what was the question?There is no punctuation, except for the last "?", so I will assume that when a word is capitalized, it starts a new sentence. Therefore the statements are:In a triangle the measure of the largest angle is 3 times the measureof the smallest angle. The measure of the remainingangle is twice themeasure of the smallest angle.Since "Measure of the largest angle" is a fragment of something, I will discard it (it could be a mistake of leftover text or could be an incomplete thought). I guess that the "?" at the end means that we are supposed to answer something, and the answer could possibly relate to the largest angle. If I supply all the angles, you will hopefully get your answer.Since L=3S and M=2S, and 3S+2S+S=180º, then 6S=180º, so Smallest angle =30ºMiddle angle =60ºLargest angle =90º


The perimeter of a triangle is 57 the first side is twice the length of the second side the third side is seven more than the second side what is the length of each side?

the perimeter of a triangle is 86 inches. the largest side is four inches less than twice the smallest side. the third side is 10 inches longer than the smallest side. what is the length of each side?
