I'm not completely sure but I think it is -5x.
Gcd(3,2)=1 Hope this helps!!
(The answer is 1)
Cos (Ф) = 0.9123
To calculate Ф, we have to find the arcos (0.9123) ≈ cos⁻¹ (0.9123)
cos⁻¹(0.9123) = Ф
cos⁻¹ (0.9123) = 24°.175
Ф = 24°.175
It is, because Lauren may have gotten a incredibly high score on the first test, and a worse one on the second, while Antoine may have gotten a horrible score for the first test.
