Given:
Angle A = 18.6°
Angle B = 93°
Length of side AB = 646 meters
To find:
the distance across the river, distance between BC
Steps:
Since we know the measure of 2 angles of a triangle we can find the measure of the third angle.
18.6° + 93° + ∠C = 180°
111.6° + ∠C = 180°
∠C = 180° - 111.6°
∠C = 68.4°
Therefore the measure of angle C is 68.4°.
now we can use the law of Sines,


![BC[sin(68.4)] = 646 [sin(18.6)]](https://tex.z-dn.net/?f=BC%5Bsin%2868.4%29%5D%20%3D%20646%20%5Bsin%2818.6%29%5D)



meters
Therefore, the distance across the river is 222 meters.

If you would like to know how many cups of raisins does Jacob have, you can calculate this using the following steps:
6/11 ... 1/2
4 7/8 cups ... 5 cups
1/2 of 5 cups = 1/2 * 5 = 5/2 = 2 1/2 cups
The correct result would be C. 2 1/2.

Answer:
-2 is Greater than -4
Step-by-step explanation:
-4 is more Negative, therefore it’s considered as Less than -2.
If u Consider the Number Line,
negative numbers(Left), 0, Positive Numbers(right)
The number on the right side is more greater than on the Left
-2 is greater because it’s nearer positive values
Therefore -2 is Greater than -4
