Answer:

a

Step-by-step explanation:

Using the tangent ratio in the right triangle

tan15° = \frac{opposite}{adjacent} = \frac{20}{x} ( multiply both sides by x )

x × tan15° = 20 ( divide both sides by tan15° )

x = \frac{20}{tan15} ≈ 74.6 ft ( to the nearest tenth of a foot )

PLEASE ANSWER Quickly!<br><br> Find the equation of the line <br><br> Y= __x + __
AysviL [449]

Answer:

y= -x+5

Step-by-step explanation:

→first you need to identify 2 points. I'm using (5,0) and (0,5)

→second you need to find the slope using y2-y1/x2-x1 as your formula

5-0/0-5= 5/-5=-1

→then you need to use y-y1=m(x-x1) formula

y-0=-1(x-5)

(distribute the -1)

y-0= -1x+5 (+5 because a negative times a negative is a positive)

(combine like terms)

y= -1x+5

→once you solve you get y= -x+5

Answer:

d = 10/72

Step-by-step explanation:

c and d vary inversely

c = k/d

Where,

k = constant of proportionality

d = 2/9 when c = 5

c = k/d

5 = k ÷ 2/9

5 = k × 9/2

5 = 9k/2

Cross product

5*2 = 9k

10 = 9k

k = 10/9

c = k/d

c = 10/9 ÷ d

c = 10/9 × 1/d

c = 10/9d

find d when c = 8

c = 10/9d

8 = 10/9d

Cross product

8*9d = 10

72d = 10

d = 10/72
