Since it gives you the y then you just plug it in, so the equation would be 5x+2(3x-7)=8.
Answer:
292.72 ft (Assuming it is to scale)
Step-by-step explanation:
Side a = 26
Side b = 26
Side c = 26
Angle ∠A = 60° = 1.0472 rad = π/3
Angle ∠B = 60° = 1.0472 rad = π/3
Angle ∠C = 60° = 1.0472 rad = π/3
C=60°B=60°A=60°b=26a=26c=26
Area = 292.71659
Perimeter p = 78
Semiperimeter s = 39
Answer:
it means less than or equal to :)
Step-by-step explanation:
Answer:
foot = 5 ft
luff = 20 ft
Step-by-step explanation:
In the picture attached, the diagram of the sail is shown. A right triangle is formed, where 50 ft² is its area, which can be computed as follows:
foot*luff*1/2 = 50
We also know that luff = 4*foot. Replacing into the previous equation:
foot*(foot*4)*1/2 = 50
foot²*2 = 50
foot² = 50/2
foot = √25
foot = 5 ft
luff = 4*5 = 20 ft
