Answer:
24°
Step-by-step explanation:
The angle between the vertical line AB and the horizontal dashed line at A is 90°. That is, ...
66° + ? = 90°
? = 90° -66° = 24°
The angle of depression is 24°.

<em>Additional comment</em>
The sum of angles in the triangle is 180°, so the angle at C (the angle of elevation) is the same as the angle we just figured:
∠C + 90° +66° = 180°
∠C +66° = 90° . . . . . . . subtracting 90°; shows C is complementary to 66°
∠C = 90° -66° = 24°
As a rule, the angle of elevation and the angle of depression are the same.
So,
If this was mental math, I would round 1.87 to the nearest pound and 2.46 to the nearest half pound, making the following addition problem:
2 + 2.5 = 4.5
Because 1.87 is closer to 2 than to 1.5 or 1, and 2.46 is sooo close to 2.5.
So I would say about 4.5 pounds of meat.
But if you're rounding to the nearest pound for both, then you have this equation:
2 + 2 = 4
Because in 1.87, 8 is greater than or equal to 5, and in 2.46, 4 is less than or equal to 5.
So in that case, it would be about 4 pounds of meat.
