Step-by-step explanation:
Answer:
It should be Neither ordered pair is a solution
Step-by-step explanation:
I take the same math lol
We have the formula (sin x)^2 + (cos x)^2 = 1;
Then, sin α =
![\sqrt{1- ( \frac{4}{5}) ^{2} } = \frac{3}{5} ;](https://tex.z-dn.net/?f=%20%5Csqrt%7B1-%20%20%28%20%5Cfrac%7B4%7D%7B5%7D%29%20%5E%7B2%7D%20%7D%20%3D%20%20%5Cfrac%7B3%7D%7B5%7D%20%3B)
cos β =
![\sqrt{1- ( \frac{4}{5}) ^{2} } = \frac{3}{5} ;](https://tex.z-dn.net/?f=%20%5Csqrt%7B1-%20%28%20%5Cfrac%7B4%7D%7B5%7D%29%20%5E%7B2%7D%20%7D%20%3D%20%5Cfrac%7B3%7D%7B5%7D%20%3B)
We apply the formula sin ( α + β ) = sin α x cos β + sin β x cos α = (3/5)x(4/5) + (4/5)x(3/5) = 12/25 + 12/25 = 24/25;
