Proof:
Given ΔGWN is an equilateral triangle.
WS ≅ WI
∠SWG ≅ ∠IWN
To prove: ΔSWG ≅ ΔIWN
In ΔSWG and ΔIWN,
WS ≅ WI (given sides)
∠SWG ≅ ∠IWN (given angles)
WG ≅ WN (Equal sides of ΔGWN)
Therefore by Side-Angle-Side(SAS) congruence rule,
ΔSWG ≅ ΔIWN
Hence proved.
Answer:
We have 8 boys and 12 girls, and we have 5 boys that have a speaking part, and 7 of the 12 girls do not have a speaking part, so 5 girls have a speaking part, which makes 10 speaking parts out of 20 so we have .
Hope this helps!
Cost per person= Total cost/ number of people
For example, if 10 people went to the movies and the total cost was $50
so 50/10= 5 dollars per person

Answer:
Area of triangle is 9.88 units^2
Step-by-step explanation:
We need to find the area of triangle
Given E(5,1), F(0,4), D(0,8)
We will use formula:
We need to find the lengths of side DE, EF and FD
Length of side DE = a =
Length of side DE = a =
Length of side EF = b =
Length of side EF = b =
Length of side FD = c =
Length of side FD = c =
so, a= 8.60, b= 5.8 and c = 4
s = a+b+c/2
s= 8.6+5.8+4/2
s= 9.2
Area of triangle=
So, area of triangle is 9.88 units^2
