8/7= 7/2x
2x= 16*7/8
2x =14
X=7
Hi there!
The answer is x = 6. All you have to do is subtract 83 from 127 because 127 is the total of the two parts of the equation. Now using the expression they give you - since you already know what the missing angle degree is for JKM- you just plug it in. 9x-10=44.
Add 10 to both sides to cancel out the ten.
You then have 9x = 54.
Divide both sides by 9.
Leaving you with x = 6.
Hope this helps !
Binary Operations
The union of two sets A and B is denoted A ∪ B and
is defined as A ∪ B = {x|x ∈ A or x ∈ B}.
The intersection of two sets A and B is denoted A∩B
and is defined as A ∩ B = {x|x ∈ A and x ∈ B}.
Two sets are disjoint if they have no elements in common,
that is, A and B are disjoint if A ∩ B = ∅.
Answer:
L=8
Step-by-step explanation:
area of a rectangle = length x width
given:
area= 20 square units
width =2.5 units
find the length by substituting :
20=2.5 x L
L= 20/2.5=8
that's it :)
