Based on the picture below:

what is the area of the triangular field is approximately square yards.

72000

Step-by-step explanation:

Look at the triangle: 450 yards and 320 yards, with 80 degrees between these two sides. Use the 450 yard side as base. You want the altitude, which can be 320%2Asin%2880%29.

AREA is  multiply the base by the height, and then divide by 2.

more simply, area is 72000 Square Yards.

hope it helps:)

i'm assuming it's looking for the missing length, which should be 4cm

hope this !

i believe it is c.y = 9x

rise over run. 9 units up over 1 unit right or 9/1
