If cos Φ8/17 find the other five trigonometric ratios​

Mathematics
1 answer:
NeX [460]3 years ago
4 0

Answer:

cos theta=8/17

8/17=A/H

finding O,

O ² + A² =H ²

(8)²+O²=(17)²

64+O²=289

O²=289-64

O²=225

O=√225

O=15

we know that H=17, A=8, O=15

therefore, the other trigonometric ratios are

sinФ=O/H=15/17

tanФ=O/A=15/8

cosecФ=H/O=17/15

secФ=H/A=17/8

cotФ=A/O=8/15

hope it helps u!

Answer:

181.818181...Miles

Step-by-step explanation:

50 = 30 + 11X

X = 181.81818181...

If you multiply 11 by 181.81 repeting you will get 20 and 30 + 20 = 50

So You would have to go 181.81 repeating miles for it to be equal

If you are rounding up it would be 182 miles to justify choosing plan B

the length of a soccer pitch is 20 m less than twice its width. the area of the pitch is 6000m^2. find its dimensions.
Setler79 [48]
X=width of a coccer pitch
2x-20=length of a soccer pitch
Area (rectangule)=length x width
We suggest this equation:
x(2x-20)=6000
2x²-20x=6000
2x²-20x-6000=0
x²-10x-3000=0
We solve this quadratic equation:

x=[10⁺₋√(100-4*1*-3000)]/2=[10⁺₋√(100+12000)]/2=
=(10⁺₋110)/2
we have two solutions:
x₁=(10-110)/2=-50, invalid solution.
x₂=(10+110)/2=60

x=60
2x-20=2(60)-20=120-20=100

Solution: the length is 100 m, and the width is 60 m.

To check:
Area=100 m*60 m=6000 m²
The twice of width is =2(60 m)=120 m,
20 m less than twice its width is: 120 m-20 m=100 m=the length.
