Explanation:
________________________________________________
All angles of any triangle must add up to 180 degrees.
So, (10x - 4) + (8x + 3) + 91 = 180 ; Solve for "x" ;
___________________________________________
10x - 4 + 8x + 3 + 81 = 180 ;
Combine the "like terms" on the left-hand side of the equation:
___________________________________________
+10x + 8x = 18x ;
- 4 + 3 + 8 = 7 ;
____________________________
18x + 7 = 180 ;
___________________________________________
Subtract "7" from each side of the equation:
___________________________________________
18x + 7 - 7 = 180 - 7 ;
___________________________________________
to get:
18x = 173 ;
_________________________________
Divide EACH side of the equation by "18" ; to isolate "x" on one side of the equation; and to solve for "x" ;
_________________________________
18x / 18 = 173 / 18 ;
_________________________________
x = 9.6111111111111111....
_____________________________________
Write as: 9.611 ; or; 9 11/18.

The answer is 110 square centimeters.
Answer:
1.5, 3.4, 1.2
Step-by-step explanation:
L = the length of the property
W = the width of the property
Area
L * W = 6
but it says," The width of the property is of 3/8 the length he property."
therefore
W = 3%2F8L
or
W = .375L
In the area equation, replace W with .375L
L * .375L = 6
.375L^2 = 6
L^2 = 6%2F.375
L^2 = 16
L = sqrt%2816%29
L = 4 mi is the length
then
.375(4) = 1.5 mi is the width
