Answer:
Because they are parallel:
Angles 1,3,5 and 7=125
180-125=55
Angles 2,4, 6 and 8=55
Hope this helps!
Solution
To find out which expressions represent the difference of exactly
two expressions
a) 6(x+7) - 2
This can be simplified as
6x + 42 - 2
6x + 40
Clearly this does not represent difference of the two
expressions .
b) -2j
Clearly this represents a single expression , this does not represent
a difference of 2 expression .
c) 4f - 2g
Here we have 2 different expressions 4f and 2g
Difference of these 2 expressions are 4f - 2g
Hence , this option represent difference of exactly two
expression
d) 3xyz - 10
3xtz - 10 represnts a single expression
Here we have a single expression
Therefore it does not represent difference of exactly 2
expression .
Answer:
- 
Step-by-step explanation:
To convert degrees to radians
radian measure = degree measure × 
, then
radian measure = - 220 × ( divide 220 and 180 by 20 )
= -
Answer:
Step-by-step explanation:
If G is the midpoint of CD, and AC is parallel to DB, then AC = DH.
Therefore, G is the midpoint of AH and ΔACE is similar to ΔDBE.
As AC : DB = 1 : 3
⇒ Area of ΔACE : Area of ΔDBE = 1² : 3² = 1 : 9
We are told that Area ΔACE = Area ΔAEG.
⇒ Area ΔACG = 2 × Area ΔACE
As AC = DH, and G is the midpoint of CD:
⇒ ΔACG ≅ ΔHDG
⇒ Area ΔHDG = 2 × Area ΔACE
Area of quadrilateral EGHB = Area of ΔDBE - Area ΔHDG
= Area of ΔDBE - 2 × Area of ΔACE
Therefore:
Using the ratio of Area ΔACE : Area ΔDBE = 1 : 9
The area would be 324 yards square. Since the height is already found, you multiply 15 by 21 2/3 yards.
Hope this helped :)
