Since the pivot pillar is 1 m above the ground, maximum angle can the seesaw beam move is 26.39°
The maximum angle can be gotten using trigonometric ratios answer the question,
<h3>What are trigonometric ratios?</h3>
Trigonometric ratios are the ratios of the sides of a triangle.
<h3>What are angles?</h3>
Angles are a measure of rotation or bearing.
Given that the seesaw plank is 4.5 m long and the pivot pillar is 1 m above the ground, when the seesaw is at maximum angle, it forms a right angled triangle with the ground.
It also forms a smaller similar triangle with the same maximum angle Ф which is gotten from the trigonometric ratio
sinФ = h/L where
- h = height of pivot pillar above ground = 1 m and
- L = length of midpoint of plank = 4.5m/2 = 2.25 m
<h3>Maximum angle seesaw beam can move</h3>
So, Ф = sin⁻¹(h/L)
= sin⁻¹(1 m/2.25 m)
= sin⁻¹(1/2.25)
= sin⁻¹(0.4444)
= 26.39°
So, maximum angle can the seesaw beam move is 26.39°

Answer:
Equation has one real root and two complex roots.
Step-by-step explanation:
The equation 
consists of two parts. The left side of this equation can be represented by the function 
and the right side can be represented by the function 
Graphs of both these functions are shown in the attached diagram.
These graphs have one common point, this means that the equation has one real solution (approximately, x≈-1.839).
Given equation is cubic, then this equation has three roots. Since only one root is real, then two remaining roots are complex.
