Answer:
- b = 757.7 m
- A = 17.2°
- C = 14.3°
Step-by-step explanation:
From the law of cosines, you can find the length of side b to be ...
b = √(a² +c² -2ac·cos(B))
b = √(184041 +128164 -307164cos(148.5°)) ≈ √574105.36
b ≈ 757.7
__
From the law of sines, you can find the measure of angle C to be ...
C = arcsin(c/b·sin(B))
C ≈ arcsin(358/757.7·sin(148.5°)) ≈ arcsin(0.246872)
C ≈ 14.3°
A = 180° -148.5° -14.3°
A = 17.2°

Some graphing calculators have built-in triangle-solving functions. Apps are available for the purpose for phone or tablet. The screenshot shows a web site that does a nice job of solving the triangle.
Answer: the slope is defined as the ratio of vertical change between two point.
Step-by-step explanation: or known as the run. The slope of a line is mostly presented by the letter m.
The answer is the first one! :)
Answer:
The amount in the first account is $5,700
The amount in the second account is $1,300
Step-by-step explanation:
Let the mount invested in the first account be 
and the one invested in the second account be 
.
Then the total principal is 
---->(1)
The interest in the first account is 
The interest in the first account is 
The total interest for the year is 262.00.
This implies that:
---->(2)
We solve the two equations simultaneously to get:
and 
Alright so the answer would be letter B, because
win-to-loss
49 to 21 (You can determine her losses by subtracted the number of wins from her total number of games played)
Now you must simplify your answer
7 is the greatest common factor (GCF) of both 49 and 21
Now divide both 49 and 21 by 7 to get
7 to 3
