</u>
Step-by-step explanation:
<u>Step 1: Define</u>
<em>Identify</em>
3 ÷ x = 6
<u>Step 2: Solve for </u><em><u>x</u></em>
- [Multiplication Property of Equality] Multiply <em>x</em> on both sides: 3 = 6x
- [Division Property of Equality] Divide 6 on both sides: 3/6 = x
- Simplify: 1/2 = x
- Rewrite: x = 1/2

Answer:
sqrt7
Step-by-step explanation:
cosA = b/3 = sqrt2 /3
so b = sqrt2
apply the pythagorean theorem
a = sqrt7
Answer:
1064 ft.
Step-by-step explanation:
Start by sketching out a figure to represent the situation, it should look something like this:
(See picture)
(Figure definitely not drawn to scale)
The angle marked in red measures 4.3°, then we can use the law of sines to solve for the height of the Eiffel Tower (represented as the variable x):
Rounding gives 1064 ft.
