Your list of numbers needs a bit of clarification.
You wrote: <span>.9,1.1,.10 38 and .10299
I have to make some assumptions here, and to ask whether you meant the following:
</span><span>.9, 1.1, .1038 and .10299
If so, now's the time to look for the smallest and the largest of these numbers. The smallest is 0.10299:
smallest
</span>
0.10299
<span>0.1038
0.9
1.1
</span>.9, 1.1, .1038 and .10299
If my list disagrees with yours, please ensure that you have copied down these four numbers correctly and then try again (on your own) to order them correctly from smallest to largest.
Angles in a triangle total 180°
180=128+5x+10+9x
180-128-10=5x+9x
42=14x
x=3
Answer:
JL = 78
Step-by-step explanation:
The shorter segment is a midline, so is half the length of the longer one.
2(5x-16) = 4x +34
5x -16 = 2x +17 . . . . . divide by 2
3x = 33 . . . . . . . . . . add 16-2x
x = 11 . . . . . . . . . . divide by 3
Then segment JL is ...
JL = 4x +34 = 4(11) +34 = 44+34
JL = 78
