Find the difference, so subtract the two and you should get the answer from earth to Venus
<span>5+x+(−2)=−8
5 + x - 2 = -8
x + 3 = -8
x = -11</span>
5x + 4x = 720
9x = 720 (divide by 9)
X= 80
In order to get the bigger ratio, which is 5, you would substitute x for 80. (I'm bad at explaining)
Work:
5(80)= 400
You can use the sum and difference identities which for cosine is cos(a+b)= cosacosb-sinasinb
