You need to find, first, the horizontal component of the inclined force (call it Wx), using an angle of 15 degrees (which is the angle between the inclined plane and the horizontal).
=> cos(15°) = Wx / 2.5 lb => Wx = 2.5 lb * cos(15°).
Second, you can find the inclined force , W, needed to produce the horizontal component Wx.
cos(33°) = Wx / W => W = Wx / cos (33°) = 2.5 lb*cos(15°) / cos(33°) = 2.88 lb
Answer: 2.88 lb

Answer:
![1.79\ m^{2}](https://tex.z-dn.net/?f=1.79%5C%20m%5E%7B2%7D)
Step-by-step explanation:
we know that
The surface area of the triangular prism is equal to
![SA=2B+PL](https://tex.z-dn.net/?f=SA%3D2B%2BPL)
where
B is the area of the triangular base
P is the perimeter of the triangular base
L is the length of the prism
<em>Find the area of the triangular base B</em>
![B=\frac{1}{2}(0.8)(0.1)=0.04\ m^{2}](https://tex.z-dn.net/?f=B%3D%5Cfrac%7B1%7D%7B2%7D%280.8%29%280.1%29%3D0.04%5C%20m%5E%7B2%7D)
<em>Find the perimeter of the triangular base P</em>
![P=(0.8+0.1+0.81)=1.71\ m](https://tex.z-dn.net/?f=P%3D%280.8%2B0.1%2B0.81%29%3D1.71%5C%20m)
we have
![L=1\ m](https://tex.z-dn.net/?f=L%3D1%5C%20m)
substitute the values and find the surface area
![SA=2(0.04)+(1.71)*(1)=1.79\ m^{2}](https://tex.z-dn.net/?f=SA%3D2%280.04%29%2B%281.71%29%2A%281%29%3D1.79%5C%20m%5E%7B2%7D)
Answer: 50
Step-by-step explanation:
From the question, we are informed that 1/3 of gym members say they spent 5 hours per week at the gym.
Assuming there are 150 people working out at the gym, the number of people that'll most likely spend 5 hours at the gym this week will be calculated by multiplying 1/3 by 150. This will be:
= 1/3 × 150
= 50 people
