Answer:
<h3>3.3</h3>
Step-by-step explanation:
Distance between AB is expressed as;
AB = √(3-0)²+(4-0)²
AB = √3²+4²
AB =√9+16
AB = √25
AB = 5
2 over 3 the distance from A to B is expressed as;
2/3 of AB
= 2/3 * 5
=10/3
= 3.3

Step-by-step explanation:
<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>
