Answer:
$27.30
Step-by-step explanation:
just do 290x6+330x3=2730
but just do this $27.30
so x is $27.30
Let's solve this problem step-by-step.
To begin with, it is important to establish the following formula:
Angle sum of all triangles = 180°
Using this formula as well as the values of two out of three of the angles given, we can identify the value of the unknown angle as displayed as the following:
Let the unknown angle = x
Make (x) the subject as displayed as the following:
Angle sum of all triangles = 180°
180 = x + 63 + 59
x = 180 - 63 - 59
x = 58°
Therefore, the measure of each of the angles is as follows:
63°
59°
58°
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.
