Write out the sum formula for sin
<span>sin(x + y) = sinxcos + sinycosx </span>
<span>Then expand sin(a + b) + sin(a - b) </span>
<span>sinacosb + sinbcosa + sinacosb - sinbcosa </span>
<span>The 2nd and 4th terms cancel and you get </span>
<span>2sinacosb</span>
When x=1 y=13 when x=3 y=19 and when x=5 y=25 you just plug the numbers in for x and solve
Step-by-step explanation:
m-(-3)>17
m +3>17
m >17-3
m>14
Hey there!!
Okay here are the steps you can follow!
9 11/12 ----> improper fraction ----> 119/12
2 8/11 ----> improper fraction ----> 30/11
119/12 - 30/11
(119/12 - 30/11) * 132
11(119) - 12(30)
1309 - 360
<u>949</u>
Is there something missing on the third option? None of the other options are wider
