Let x = height of building
We use basic trigonometry to find x.
The tangent function = opposite side of right triangle OVER adjacent side of right triangle.
tan(2°) = x/1
Solve for x.
After multiplying both sides by 1 (here 1 represents 1 mile), we get
tan(2°) = x.
We now use the calculator to find x.
In fact, you can take it from here. Use your calculator.
Answer:
They will each have painted 8 km. This goal will be met on Day 4.
Step-by-step explanation:
Group A | Group B
Start: 2 | Start: 5 Day 1
2 + 2 = 4 | 5 + 1 = 6 Day 2
4 + 2 = 6 | 6 + 1 = 7 Day 3
6 + 2 = 8 | 7 + 1 = 8 Day 4
