Answer:
12 fraction 3/4, 12.39, 12.65 and, 12 fraction 5/8
Step-by-step explanation:
The inside angles of a six sided figure need to equal 720 degrees.
The total of the given angles is: 112 + 133 + 128 + 100 + 120 = 593
X = 720 - 593 = 127 degrees.
Answer:
A reasonable estimate is [tex]1,900 * 300 = 570,000[tex]
Step-by-step explanation:
This is because 1,900 is the closest multiple of 100 for 1,912, and 300 is the closest multiple of 100 for 305. And [tex]1,900 * 300[tex] is [tex]19 * 3 * 10,000[tex].
Answer:
8.2
Step-by-step explanation:
Area of triangle is calculated by multiplying height to the base and that divided by two
20 × h ÷ 2 = 56^2
h = 5.6
The square length of CD is equal to sum of square length of height and base
6^2 + 5.6^2 = CD^2
CD = 8.2
