Answer:
The two possible distance are 147.5km and 64.4km
Step-by-step explanation:
Given
<em>See Attachment for Illustration</em>
Required
Determine the possible distance of ship A from the boat
The distress is represented by X;
So, the question requires we calculate distance AX;
This will be done using cosine formula as follows;
In this case;
a = 70;
b = ??
x = 120
A = 28 degrees
Substitute these values in the formula above
Subtract 4900 from both sides
Solve using quadratic formula
Substitute 1 for a; -211.9 for b and 9500 for c
This can be splitted to
or
or
or
<em>Hence, the two possible distance are 147.5km and 64.4km</em>
Answer:
Step-by-step explanation:
The grouping of the multiplicands has changed, but the end result will be the same.
In mathematics, a ratio is a relationship between two numbers indicating how many times the first number contains the second. For example, if a bowl of fruit contains eight oranges and six lemons, then the ratio of oranges to lemons is eight to six (that is, 8:6, which is equivalent to the ratio 4:3). Thus, a ratio can be a fraction as opposed to a whole number.The ratio for 12:8 is 6:4
