In triangle mno, mn = 20 units, no = 15 units, and mo = 18 units. what is the approximate difference between the largest and smallest angle measures?

The approximate difference between the largest and smallest angle measures is 28 degrees

Step-by-step explanation:

In any triangle , angle opposite to the largest side will be largest .

Thus largest angle will be ∠MON

Using cosine rule

=>

And angle opposite to the smallest side will be smallest

Thus smallest angle will be ∠OMN

Using cosine rule

=>

Therefore difference between largest angle and smallest angle ,

Thus the approximate difference between the largest and smallest angle measures is 28 degrees

step-by-step explanation:

the line of
