Step-by-step explanation:
The largest angle is opposite the largest side and the smallest angle is opposite the shortest side.
Δ FUN
largest angle is ∠ FUN ( opposite FN )
smallest angle is ∠ NFU ( opposite NU )
Δ GEO
largest angle is ∠ GEO ( opposite GO )
smallest angle is ∠ GOE ( opposite GE )
---------------------------------------------------------------------------
The longest side is opposite the largest angle and the shortest side is opposite the smallest angle.
∠ RTY = 180° - (70 + 55)° = 180° - 125° = 55°
Δ TRY is therefore isosceles with 2 congruent legs RT, RY
longest side is TY ( opposite 70° )
shortest sides are RT , RY ( opposite 55° )

It's a number that is less than 38
Answer:
Each side of the hexagon is a rectangle of height 4ft and width 11ft.
The area of each one of these rectangles is:
A = 4ft*11ft = 44ft^2
And a hexagon has 6 faces, so the fish tank will have 6 of these rectangles, then the total area is:
area = 6*44ft^2 = 264 ft^2
We know that the base of the hexagon is not made of glass, but we do not know if the top is made of glass or not.
In the case that the top is not made of glass, the amount of glass needed is 264 ft^2
If the top is made of glass, then we need to add the area of a hexagon of side 11 ft, which is:
a = (3*√3)*(11ft)^2/2 = 314.4ft^2
Then the total area in this case is:
264 ft^2 + 314.4ft^2 = 578.4 ft^2
This is the total amount of glass needed to construct the tank if the top of the tank is made of glass.
Answer: 74.6
we draw a right triangle ABC, have: ∠ABC = 90°, AB = 20 and ∠BAC = 75°, the height of the building is BC
we also have: tan 75° = BC/AB = BC/20
=> BC = tan 75°. 20 = 40 + 20√3 ≈ 74.6
