Answer:
The fourth angle = 60°
Step-by-step explanation:
the sum of the interior angles of a quadrilateral is 360°.
The fourth angle = 360° - 100° - 120° - 80° = 60°
A = 81 square in.
s = sqrt(A)
s = sqrt(81)
s = 9 in.
Since all sides of the square are equal, therefore area of square can be calculated using the following rule:
area of square = side^2
200 = (side length)^2
therefore,
the length of each side is sqrt(200) = 14.14 ft
2kg=2000g so do 275/2000 and cancel down to 11/80 :)
