Use the sin(a - b) formula.
<span>sin(90 - x) = </span>
<span>sin90 cosx - cos90 sinx = </span>
<span>1 cosx - 0 sinx = </span>
cosx
we know that

Answer:
Alejandro received 6.51 million of votes
Laine received 58% of votes
Step-by-step explanation:
If the ratio of "Laine votes" to "Alejandro votes” was 29:21, then the number of "Laine votes" was 29x and the number of "Alejandro votes” was 21x. In total, 15.5 million votes were cast. So
29x + 21x = 15.5 million
50x = 15.5 million
x = 0.31 million
Then
the number of "Laine votes"
million
number of "Alejandro votes”
million
Laine received

2x + y = z
WHEN SOLVING FOR X :
2x + y = z
We just need to isolate x, so subtract y from both sides.
2x = -y + z
Then, divide both sides by 2.
2x ÷ 2 = -y + z ÷ 2
Simplify.
x = -y + z / 2 →

WHEN SOLVING FOR Y :
2x + y = x
We need to isolate y, so subtract 2x from both sides.
y = x - 2x
Simplify.
y = -x
