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: 173,375 miles
Step-by-step explanation:
Hi!
475 miles a day times 365 days = 173,375 miles a year!
Hope this helps
We need to convert the given measures from yard to feet. Since 1 yard is equal to 3 feet, we have
similarly, for the wide, we have
Since the area of a rectangle is wide times length, the area is
Therefore, the area is equal to 189 square feet
The answer is 5÷90+8 and that's the answer does the answer
