Triangle Z W X is shown. Angle Z W X is a right angle. An altitude is drawn from point W to point Y on side Z X to form a right angle. The length of W X is b, the length of X Y is a, the length of Y Z is 5, and the length of W Y is 6.
What is the approximate value of b, rounded to the nearest tenth?

7.2 units
7.8 units
8.6 units
9.4 units

b ≈ 9.4 units

Step-by-step explanation:

Δ WZY and Δ XWY are similar triangles, thus the ratios of corresponding sides  are equal, that is

= =

Calculate WZ using Pythagoras identity in right triangle WZY

WZ² = 5² + 6² = 25 + 36 = 61 ( take the square root of both sides )

WZ = ≈ 7.81

Substituting value into the ratio

=

= ( cross- multiply )

5b = 46.86 ( divide both sides by 5 )

b ≈ 9.4 ( to the nearest tenth )

6,250

step-by-step explanation:

to get the area, multiply 360 by 160.(57,600)

to find out how many bags of fertilizer it will take, first figure out how many square feet one bag can hold. divide 1000 by 8(125) to get the unit rate(how many square feet one pound of fertilizer can hold)and multiply it by 50(6250). if i haven't made a mistake, that is the answer.
