Answer:
⇒ 40 cm
Step-by-step explanation:
Given:
Height of cubes used by Nelson = 8 cm
Height of cubes used by Andrews = 10 cm
Solution:
Nelson made a stack of cubes where the height of the cubes is 8 cm, so the multiplication of the cube height is.
⇒ 
Similarly Andrew also made a stack of cubes where the height of the cubes is 10 cm, so the multiplication of the cube height is.
⇒ 
We can see the shortest same height of the both stack is 40 cm.
Therefore, 40 cm is the shortest possible stake height for both.
<span>(A) Find the approximate length of the plank. Round to the nearest tenth of a foot.
Given that the distance of the ground is 3ft.
In order to get the length of the plank,
we can use the this one.
cos 49 = ground / plank
cos 49 = 3 / plank
plank = cos 49 / 3
plank = 0.10 ft
</span><span>(b) Find the height above the ground where the plank touches the wall. Round to the nearest tenth of a foot.
</span><span>
The remaining angle is equal to
angle = 180 - (90+49)
angle = 41
Finding the height.
tan 41 = height / ground
tan 41 = height / 3
height = tan 41 / 3
height = 0.05 ft.
(A) 0.10 feet
(B) 0.05 feet</span>
