I give Brainliest! Using Angle Side Relationship Theorem, use the side measures to list the angle measures of the triangle in order from biggest to smallest.
Q
R
P

∠Q, ∠P, ∠R

From largest to smallest.

Step-by-step explanation:

Remember that the largest side is always opposite from the largest angle.

26 is the longest side. The angle opposite is 26 is ∠Q. So, ∠Q is the largest angle.

21 is the second longest side. ∠P is the angle opposite to 21. So, ∠P is the second largest angle.

Finally, 17 is the shortest side and ∠R is opposite to 17.

So, ∠R is the smallest angle.

Therefore, the measures of the angles from biggest to smallest is:

∠Q, ∠P, ∠R

step-by-step explanation:

14.3

step-by-step explanation:

add all the numbers together.

9 + 12 + 15 + 16 + 17 + 17 = 86

now, divide 86 by how many numbers we have: 6.

86 / 6 = 14.3
