Hello!
Supplementary angles sum up to 180°, therefore:
m∠1 + m∠2 = 180°
x - 17 + x + 83 = 180°
Combine like terms:
2x + 66 = 180°
Subtract 66 from both sides:
2x = 114°
Divide both sides by 2:
x = 57°
Find the measures of both angles using this value:
m∠1 = 57 - 17 = 40°
m∠2 = 57 + 83 = 140°

Answer:
7d-5
Step-by-step explanation:
A regular pentagon has 5 sides of equal length.
The perimeter of a regular pentagon is given by
P = 5s where s is the side length
35d -25 = 5s
Divide each side by 5
(35d-25)/5 = 5s/5
7d-5 =s
Each one of the sides is equal to 7d-5

Answer:
5 meters
Step-by-step explanation:
We should derive an equation to solve this problem.
Let's assign x to width and y to length.
and
so
Width = 5 meters
