In a parallelogram, two angles are equal and another two angles are equal. The total amount of angles is 360.124 * 2 = 248. 112 / 2 is 56. The answer is 56.
So you make your equation 4x+20+40=180.
Add like terms and get 4x+60=180.
Subtract 60 from both sides, get 4x=120.
Divide boths sides by 4, get your answer of x=30.
Hope this helps
Answer:
19.25 inches
Step-by-step explanation:
x^2 + 5^2 = 8^2= 64
25+ x^2 = 64
x^2 = 64-25= 39
x = 6.24
perimeter = 19.24
