Answer:
116 degrees
Step-by-step explanation:
well from the picture we know this is a 45 45 90 style triangle therefore in if CBE is equal to 32 then ECB should also be equal to 32 leaving you with a total number of 64 degrees within the triangle. and in every triangle you must add up the degrees to 180 so if we subtract 64 from 180 we get 116 degrees for BEC
Answer:
12+4=4+12
2+7+0=2+7
17+(-17)=0
Step-by-step explanation:
first one is clear
second one is a associative property
third onw can be because 2+7+0 is 14 and 2+7 is also 14
17 +(-17) is 0 and the other side it is zero
Answer:
123.8 units
Step-by-step explanation:
The vertices of the polygon has been labelled ABCDEF, as shown in the diagram attached below.
Perimeter of the Polygon = 
= |-12 - 24| = |-36| = 36 units
: calculate the distance between B(24, 16) and C(15, 3) using the distance formula.
= |6 - 15| = |-9| = 9 units
= |3 -(-12)| = |-15| = 15 units
= |-12 - 6| = |-18| = 18 units
= |18 -(-12)| = 30 units
Perimeter = 36 + 15.8 + 9 + 15 + 18 + 30 = 123.8 units
