Using similar right-angled triangle w/ sides 3,4,5, a=20*3/5=12

sinA=12/20=3/5
cosA=16/20=4/5
tanA=12/16=3/4
cscA=20/12=5/3
secA=20/16=5/4

a^2 + b^2 = c^2

a = sqrt(c^2 - b^2) = sqrt (20^2 - 16^2)

= 12

sin\theta = a/c = 12/20

= 3/5

cos\theta = b/c = 16/20

= 4/5

tan\theta = a/b = 12/16

= 3/4

csc\pi = c/a = 20/12

= 5/3

= 1 2/3

sec\pi = c/b = 20/16

= 5/4

= 1 1/4

Aleksandr [31]

Answer:

5

Step-by-step explanation:

for the first gear

revolutions/teeth

1 / 24

2 / 48

3 / 72

4 / 96

5 / 120

6 / 144

for the second gear

revolutions/teeth

1 / 40

2 / 80

3 / 120

4 / 160

<em>the two marks will meet after 120 teeth, 5 revolutions of the first gear and 3 revolutions of the second.</em>

the way to get that amount of teeth is

24 = 2 \times 2 \times 2 \times 3 =  {2}^{3}  \times 3

40 = 2 \times 2 \times 2 \times 5 =   {2}^{3}  \times 5

the Least Common Multiple equals the product of all factors, but those factors who are repeted for both numbers should be only once.

{2}^{3} \times 5 \times 3 = 120

120 teeth are 5 revolutions for gear1 and 3 por gear2

Whats an equation that the passes through (-6,4) and is parallel to y=1/2x+8
Trava [24]
Formula y-y1= m(X-X1)
Since its parallel the m is 1/2
The -6 is X1 and the 4 is y1
Okay now do formula

Y-4= 1/2(X--6)
Y-4= 1/2X+3
Add 4

Y= 1/2x +7
