Answer:
256^2 ft
Step-by-step explanation:
so we are going to seperate this into four triangles to make this easier the equation for the area of a triangle is (L*H)/2
10x12.8=128
128/2=64
64x4=256^2
Answer:
AC = √105 ≈ 10 cm (nearest whole number)
Step-by-step explanation:
Use Pythagoras' Theorem: a² + b² = c²
(where a and b are the legs, and c is the hypotenuse of a right triangle)
Give one of the legs = 4cm and the hypotenuse = 11 cm:
⇒ 4² + AC² = 11²
⇒ 16 + AC² = 121
⇒ AC² = 121 - 16
⇒ AC² = 105
⇒ AC = ±√105
As distance is positive, length of AC = √105 ≈ 10 cm (nearest whole number)
Answer:
235.54 N
Step-by-step explanation:
Since this is an addition of vectors, we need to find the components of each in the x-y plane. Given that the first vector (100 N) is along the x axis, it consist of just x component of size: 100N.
For the second vector, its x-component will be given by the cosine projection on the x axis via:
x-component ![=150*cos(40^o)=114.9](https://tex.z-dn.net/?f=%3D150%2Acos%2840%5Eo%29%3D114.9)
and its y-component will be given by the "sine" projection:
y component ![=150*sin(40)=96.42](https://tex.z-dn.net/?f=%3D150%2Asin%2840%29%3D96.42)
Therefore the addition of the x-components for the final vector is:
100N + 114.9N = 214.9 N
Now we use the Pythagorean theorem to find the magnitude of the resultant addition of vectors:
![\sqrt{96.42^2+214.9^2} =\sqrt{55478.8264} =235.54 N](https://tex.z-dn.net/?f=%5Csqrt%7B96.42%5E2%2B214.9%5E2%7D%20%3D%5Csqrt%7B55478.8264%7D%20%3D235.54%20N)
