Answer:
Step-by-step explanation:
3y = -2x - 5
y = -2/3x - 5/3
perp: 3/2
y - 1 = 3/2(x + 6)
y - 1 = 3/2x + 9
y = 3/2x + 10
Answer:
False
Explanation:
Because to events are disjoint if they have no outcomes in common. In other words the events are disjoined if knowing that one of the events occurs we know the other event not occur.
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.
