Explanation: i just sacrificed my answer to find the right answer
The equations that could be used to solve for the unknown lengths of ABC are; A: sin(45°) = BC/9 and E: cos(45°) = BC/9
What are missing lengths of a triangle?
The triangle is missing but from online sources, the hypotenuse of the triangle is 9 while the opposite side is AB and the adjacent side is BC.
From trigonometric ratios, we know that sin 45° = cos 45°.
Thus, we can say that;
sin(45°) = BC/9
Although from the question,
sin(45°) = AB/9, but since sin(45°) = cos 45, we can easily say that sin(45°) = BC/9 and cos(45°) = BC/9
