sergey [27]3 years ago
8 0

Answer:

x = 100

Step-by-step explanation:

the sum of the 3 angles in a triangle = 180°

Sum the 3 angles and equate to 180

52 + 28 + x = 180

80 + x = 180 ( subtract 80 from both sides )

x = 100

a farmer has one square mile of land if he divides his land into square fields that are half mile long and half my wife how many
jok3333 [9.3K]
He would have four fields. Since the area of 1/2 milex1/2 mile is 1/4, and 1x1 is 1, so 4 fields make up the land.
