Answer:
x = 8
Step-by-step explanation:
All sides are equal in terms of symmetry, such as the 5 and 5 opposite the angle 120 that repeats itself at the centre 3 times
Cancel out the terms from one side first then do it for the other one. 4 example make x and individual by multiply the other side by 9 the evaluate. do the same for y
You are correct with 80 on that answer. because since it is a polygon all sides add up to 180. you take 180 and subtract the number u have which is 100. u can double check your answer by looking at the angle. by looking its definitely less than 90 and not more than 90. it looks 80 to me and you can prove it by doing this 180-100=80
ANSWER=80°
Perimeter of circular area = πr = 3.14 * 10 = 31.4 mm
Perimeter of rectangular area = 30 + 20 + 30 = 80 mm
Total Perimeter = 80 + 31.4 = 111.4
In short, Your Answer would be 111.4 mm
Hope this helps!
