In scalene triangle abc angle b is 45 degrees, and angle c is 55 degrees.
what is the order of the sides in length from longest to shortest

First, let's find angle A.

The angles of a triangle always add up to 180 degrees.
A + B + C = 180
A + 45 + 55 = 180
A + 100 = 180
A = 80 degrees

The longest side is always opposite the largest angle.
Since A is the largest angle, the longest side is BC.
The next largest angle is C, and the next longest side is AB.
And the smallest angle B gives us the shortest side AC.

Therefore, your answer would be BC, AB, AC.

The area tom the right of the z-score of 2.75 under a statistical normal distribution curve will be given by:
1-P(z≤2.75)
but
P(z≤2.75)=0.997
thus
1-P(z≤2.75)
=1-0.997
=0.003
0.003
