What is the trigonometric ratio for sin C

Mathematics
1 answer:
Arturiano [62]3 years ago
7 0
For this case we use the following definition:
 sine (x) = (C.O) / (h)
 Where,
 x: angle
 C.O: opposite leg
 h: hypotenuse
 Substituting values:
 sine (C) = (C.O) / (h)
 sine (C) = (AB) / (82)
 We look for AB by Pythagorean theorem:
 AB = root ((82) ^ 2 - (80) ^ 2)
 AB = 18
 Substituting:
 sine (C) = (18) / (82)
 Simplifying:
 sine (C) = (9) / (41)
 Answer:
 the ratio is:
 sine (C) = (9) / (41)

If Mike does his mathematics homework today, the probability that he will do it tomorrow is 0.8. The probability that he will do
harina [27]

Answer:

d. 14:11

Step-by-step explanation:

There is a 7 in 10 chance that Mike does his homework today and a 8 in 10 chance he will do it tomorrow,  the probability that he will do it both today and tomorrow is:

P = \frac{7}{10}* \frac{8}{10}\\P=\frac{56}{100}=0.56

The odds are the probability that an event occurs over the probability that it does not occur:

Odds = \frac{0.56}{1-0.56}=\frac{56}{44}=\frac{14}{11}

The odds that he will do it both today and tomorrow are 14:11.

10 men and 5 women are meeting in a conference room. Four people are chosen at random from the 15 to form a committee. (a) What
nata0808 [166]

Answer:

Step-by-step explanation:

Given

There are 10 men and 5 women in a conference room

total People=15

(a)Probability that the committee consists of 2 men and 2 women

we have to select from 10 men and 5 women

P=\frac{^5C_2\times ^{10}C_2}{^{15}C_4}

(b)Bob and Jane end up on the same committee

as bob and Jane are necessary to include so there are 4 women and 9 men left to select remaining 2 person

P=\frac{^{13}C_2}{^{15}C_4}

(c)Bob is in the committee but Jane is not

9 men and 4 women left to choose other 3 person

P=\frac{^{13}C_3}{^{15C_4}}

Can you help me? sin 35 (degrees) Thanks!
Nata [24]
<span>OK, here's a *very* approximate "creative" method: 
</span><span>
sin(a+b)=sin(a)cos(b) + cos(a)sin(b) </span>
<span>
choose a=30deg and b=5deg </span>
- sin(a)=0.5 (exact) 
- b is a small number so we say sin(b)~b (in radians). We can do a long division for this: 3.14/36 = 0.087 radians 
- similarly, for b sufficiently small, cos(b)~1 
<span>- now we only need cos(a) = sqrt(3)/2. We can approximately calculate sqrt(3) as 1.73, (by trial-and-error or better, by using the Babylonian method;  so sqrt(3)/2 = 0.865 </span>
<span>
Finally, sin(30 + 5) = (0.5 x 1) + (0.087 x 0.865) = 0.575 (calculating more digits is of no use because the sin(b)=b and cos(b)=1 are quite inaccurate approximations). </span>

<span>So that wasn't all too much effort, and we're close to the correct answer (0.574)


I hope my answer has come to your help. Thank you for posting your question here in Brainly. We hope to answer more of your questions and inquiries soon. Have a nice day ahead!
