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

Answer:
(5,4)
Step-by-step explanation:
We have that the longer base of an isosceles trapezoid joins points (-3, -2) and (7, -2), and one endpoint of the shorter base is (-1, 4).
The best way to find the coordinates of the other endpoint is to draw or sketch the figure on a coordinate grid.
From the graph in the attachment the coordinates of the other endpoints is (5,4).
