Answer:
The last one
Step-by-step explanation:
Actually I think it's a correct answer .
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.

Question.... Why no links, i wont give you any, but why does everyone dislike links? Just so u know in am 9 and i am in high school :)
Step-by-step explanation:
From 2 to 101 , the perfect square numbers are ,
- 4 , 9 , 16 , 25 , 36 , 49 , 64 , 81 , 100 .
Total number of possible outcomes = 100.
Total number of favourable outcomes = 9 .
Hence ,
→ <u>P ( of getting perfect square ) = 9/10</u><u>0</u>
