Given the side lengths, determine whether thr triangle is acute, right, ovtuse, or not a triangle: 20, 23, 41

1) If sum of the two smaller sides of a triangle is greater than the third longer side, then its a triangle.

Use the side lengths to classify the triangle as acute, right, or obtuse. Compare the square of the length of the longest side with the sum of the squares of the lengths of the two shorter sides

2) Square root of sum of the squares of the two smaller sides is equal to the third longer side, then its a right triangle.

In our case,

√20^2+23^2≈30.4795<41.

Since the sum of the squares of the two shorter sides is < the square of the longer side, its an obtuse angle triange

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
