Answer:
0.
Step-by-step explanation:
The angle whose sine is 5/12 = 22.62 degrees and in Quadrant II it is
180 - 22.62 degrees
The angle whose tan is (5/12) = 22.62.
So we can write α as 180 - α and β as α.
sin (α+β) = sin ( 180 - α = α) = sin 180
= 0.
Answer:
-6/5
Step-by-step explanation:
solution;
let,the number be x,
product of <u>twice</u><u> </u><u>of</u><u> </u><u>x</u> and <u>six</u> = the <u>difference </u>
<u>difference of eleven times x and 6/5</u>
or, (2x×6)=(11×x)-(6/5)
or, 12x = 11x - 6/5
or, 12x - 11x = -6/5
therefore,x =-6/5
Therefore, the number required is (-6/5) whose product of twice a number and six is the same as the difference of eleven times the number and 6/5 .
