No, Alex is wrong. The correct expanded form would be 100+60+5+.03+.008
Answer:
Step-by-step explanation:
look at the pictures. they should help.
when you have a triangle and you are trying to find the exterior angle you need to find the interior angle that is opposite of the exterior angle. they should both add up to 180 because it will be on a straight line. what ever numbers you have left should be for both angles.
Step-by-step explanation:
Let's say the position of the fire is point C.
Bearings are measured from the north-south line. So ∠BAC = 55°, and ∠ABC = 60°.
Since angles of a triangle add up to 180°, ∠ACB = 65°.
Using law of sine:
190 / sin 65° = a / sin 60° = b / sin 55°
Solving:
a = 181.6
b = 171.7
Station A is 181.6 miles from the fire and station B is 171.7 miles from the fire.
Answer:
Change the fractions so the denominators match then add the two terms together.
