Answer:
19.1 miles
Step-by-step explanation:
The situation given represents a right triangle.
Thus, we would use trigonometric function to find how far north the boat travelled.
Let's represent how far the boat travelled north with "x".
Thus:
Reference angle = 23°
Opposite = x
Adjacent = 45 miles
Apply TOA:
Tan 23° = Opp/Adj
Tan 23° = x/45
Multiply both sides by 45
45 × Tan 23° = x
x = 45 × Tan 23°
x = 19.1013667
x = 19.1 miles (nearest tenth of a mile)
Answer:
1/5 is the simplified answer to 4/20.
Step-by-step explanation:
When you divide the numerator and denominator by 4, you get the simplified fraction of 1/5.
Longest is 6x^2+8
half of that is 3x^2+4
perimiter=sum of sides
so
6x^2+8+12x-3+3x^2+4=
9x^2+12+9
