70%=0.7
140/0.7=200
Therefore, 140 is 70% of 200.
Hope this helps!
Answer:
A
Step-by-step explanation:
Answer:
F = 254.08N Θ = 72.03°
Step-by-step explanation:
First of all we find the resolution in both x and y axis
∑Fx = 170cos87 + 100cos46 = 78.36N
∑Fy = 170sin87 + 100sin46 = 241.70N
To find the resultant vector we use pythagorean theorem
F = √(∑Fx)² + ∑(Fy)²
F = √(78.36² + 241.70²)
F = √(64559.1796)
F = 254.08N
the angle between both force can be obtained using
tanθ = ∑Fy / ∑Fx
tanθ = 241.70 / 78.36
tanθ = 3.084
Θ = tan⁻ 3.084
Θ = 72.03°
Answer:
false
Step-by-step explanation:
Bonjour,
Soit c le côté de l' hexagone.
On a 5.2²+(c/2)²=c²
==>c²=5.2*4/3
c²=104/15
c=√(104/15)=2,6331223544175332023251281391631...
Aire de l'hexagone= 5.2*c/2*6=41,076708728913517956271998970944
