Answer:
Staples, Bestbuy, Maybe Homedepot
Explanation:
The distance from the vertical beam that the lower end of the support beam be placed along the horizontal floor is 3.00 m
<h3>Angle of elevation</h3>
The angle of elevation is the angle to which the eye must be raised in order to see an elevated obect at a height.
Now, we know that a right angle triangle is formed; we can obtain the distance from the vertical beam that the lower end of the support beam be placed along the horizontal floor from;
tan 28 = 1.6/x
x = 1.6 /tan 28
x = 3.0 meters

Answer:
3740N
Explanation:
The magnitude of the net force acting on an object is equal to the mass of the object multiplied by the acceleration of the object as shown in the formula below. If the net force acting on an object is zero, then the object is not accelerating and is in a state that we call equilibrium.
The formula for force is force = mass x acceleration.
To find mass, simply divide the force by the acceleration
acceleration=1.1m/s²
Mass=4500−760=3400N
Therefore, Mass x acceleration
=1.1m/s²x3400=3740N
Complementary angles are those whose sum is 90 degrees, right?, then let's find A, A=72 degrees, because its mid point is 36 deg. Then, B = 18 degrees and its mid point is 9 degrees! :)
