creativ13 [48]
Let the price of game, marker, pen and book be $w, x, y and z.

x =  \frac{1}{3} y
y =  \frac{1}{3} z
z =   \frac{1}{3} w
x =  \frac{1}{3} y \\ x =  \frac{1}{3} ( \frac{1}{ 3} z) \\ x =  \frac{1}{3} ( \frac{1}{3} ( \frac{1}{3} w) \\ x =  \frac{1}{27} w

<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>
