We can drop the absolute value and the signs, and the integer part if they're all the same, and then make a common denominator and check for a decreasing sequence.
10/12, 7/12, 5/12 -- Check decreasing
3 1/3, 3 2/3, 2 2/3 -- nope, increases then decreases
6 5/7, 6 3/7, 5 2/7 - Check, decreasing
11 7/10, 11 6/10, 10 3/10 -- Check, decreasing

Answer:
The measurement of arc KL is ![8\°](https://tex.z-dn.net/?f=8%5C%C2%B0)
Step-by-step explanation:
Let
x--------> the measure of arc KL
y-------> the measure of arc MJ
we know that
The measurement of the outer angle is the semi-difference of the arcs it encompasses.
so
![m](https://tex.z-dn.net/?f=m%3CMEJ%3D%5Cfrac%7B1%7D%7B2%7D%28y-x%29)
we have
![m](https://tex.z-dn.net/?f=m%3CMEJ%3D16%5C%C2%B0%5C%5C%20y%3D5x)
substitute the given value
![16\°=\frac{1}{2}(5x-x)\\ 32\°=(4x)\\ x=8\°](https://tex.z-dn.net/?f=16%5C%C2%B0%3D%5Cfrac%7B1%7D%7B2%7D%285x-x%29%5C%5C%2032%5C%C2%B0%3D%284x%29%5C%5C%20x%3D8%5C%C2%B0)
therefore
The measurement of arc KL is ![8\°](https://tex.z-dn.net/?f=8%5C%C2%B0)

Step-by-step explanation:
Answer:
<h2>D = 28°</h2>
Step-by-step explanation:
To find angle D we use tan
tan ∅ = opposite / adjacent
From the question
DE is the adjacent
EF is the opposite
DE = 13
EF = 7
tan D = 7/13
D = tan-¹ 7/13
D = 28.3°
D = 28° to the nearest tenth
