Find the exact value of sin –255°.
alekssr [168]

Answer:

sin(-255°) = √2 + √6/4

Step-by-step explanation:

We need to find sin -255°

We know that sin(-a) = - sin(a)

so, sin(-255°) = - sin 255°

We know that 180° + 75° = 255°

Now we can write sin(255°) = sin(180° + 75°)

We can use the identity:

sin(x+y) = sin(x) cos(y)+cos(x)sin(y)

x = 180° , y = 75°

Solving,

sin(x+y) = sin(x) cos(y)+cos(x)sin(y)

sin(180° + 75°) = sin(180°) cos(75°)+cos(180°)sin( 75°)

sin(180°)  = 0

cos(75°) = √6 -√2/4

cos(180°) = -1

sin( 75°) = √2 + √6/4

Putting values,

sin(180° + 75°) = 0 (√6 -√2/4) + (-1)(√2 + √6/4)

sin(180° + 75°) = -(√2 + √6/4)

We know that sin(-255°) = -sin(255°)

Putting value of sin(255°)

sin(-255°)  = -(-(√2 + √6/4))

sin(-255°) = √2 + √6/4

PLEASE HELP!
den301095 [7]

Answer:

7 percent

Step-by-step explanation:

We have the following information from the question:

The probability that a student chooses art as an elective is 15 percent: P(A)=15\%

The probability that a student chooses art or drama is 20 percent: P(A\cup D)=20\%

The probability that a student chooses both art and drama is 2 percent:

P(A\cap D)=2\%

Recall that:

P(A\cup D)=P(A)+P(D)-P(A\cap D)

We plug in the various probabilities to get:

20\%=15\%+P(D)-2\%

20\%-15\%+2\%=P(D)

7\%=P(D)

\therefore P(D)=7\%

Hence the probability that a student chooses drama as an elective is 7 percent

Pq has a length of 17 units with p(-4,7). If the x and y coordinates of q are both greater than the x and y coordinates of p wha
prisoha [69]

Answer:

Step-by-step explanation:

1²+16²=1+256=257≠289(17²)

2²+16²=4+256=260≠17²

3²+16²=9+256=265≠17²

4²+16²=16+256=272≠17²

5²+16²=25+256=281≠17²

6²+16²=36+256=292>17²

6²+15²=36+225=261≠17²

7²+15²=49+225=274≠17²

8²+15²=64+225=289=17²

9²+14²=81+196=277≠17²

10²+14^2=100+196>289

10²+13²=100+169=269≠17²

11²+13³=121+169=290>17²

11²+12²=121+144=265≠17²

12²+12²=144+144=288≠17²

so only integer values are 8²+15²=17²

(x+4)²+(y-7)²=17²

if x+4=8

x=8-4=4

y-7=15

y=15+7=22

so q is (4,22)

if x+4=15

x=15-4=11

y-7=8

y=8+7=15

point is (11,15)
