Answer:
Step-by-step explanation:
So the first thing to do is get the number of angles inside this pentagon, which is 540 degrees. One way to do this is that you know a pentagon is formed of 3 triangles and since there are 180 degrees in a triangle, 3x180=540
Then it is algebra
540=91+125+92+(3x-5)+(4x-8)
Simplify what you can and collect like terms
540=308+3x-5+4x-8
540=308+7x-13
Then move everything over to the one side so that the variable is isolated
540-308+13=7x
245=7x
242/7=x
35=x
19.37cm is 74.5% of 26cm so we then we need to take away 19.37 from 26cm that leaves us with 6.63
hope i helped was quite hard just remember the way i did it

Answer:
5 + x
Step-by-step explanation:
x more than 5 is 5 + x
Answer:
Length = 9 inches
Width = 13 inches
Step-by-step explanation:
Since width is 4 inches more than the length, we can let length be x, and so width would be x + 4
So we can say;
Perimeter = 2(L + W)
44 = 2{ (x) + (x+4) }
44 = 2 (2x + 4)
44 = 4x + 8
44 - 8 = 4x
36 = 4x
36/4 = x
9 = x
Since Length = x, length = 9
and since width = x + 4, width = 9 + 4 = 13
Hope this helps!
