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)

Question:
Write an algebraic expression for how many miles Mr.Stein drove.
Answer:
(70 - y) miles
Step-by-step explanation:
Given
Distance to business meeting from office = 70 miles
Mr. Smith drove the first y miles
Let x = the remains distance driven by Mr. Stein
x + y = 70 ---- Make x the subject of formula
x = 70 - y
So, the expression is (70 - y) miles
