Answer:
AB or the distance across the river is about 171.36 meters.
Step-by-step explanation:
Please refer to the diagram below (not to scale). The area between the two blue lines is the river.
To find AB, we can use the Law of Sines. Recall that:

BC (or <em>a</em>) is opposite to ∠A and AB (or <em>c</em>) is opposite to ∠C. Thus, we will substitute in these values.
First, find ∠A. The interior angles of a triangle must total 180°. Thus:

Substitute:

Solve for ∠A:

Substitute BC for <em>a</em>, AB for <em>c</em>, 49.5° for <em>A</em> and 18.3° for <em>C</em> into the Law of Sines. Thus:

Since BC = 415 m:

Solve for AB. Cross-multiply:

And divide:

Use a calculator. Hence:

AB or the distance across the river is about 171.36 meters.

First you to explain what your trying to say. you said that The overnight temperature in Tampa never reached below 40 f during November which inequality shows that? does it end there? shows what? I have no idea I can not add, subtract, times, or divide. Can you tell me the rest of you question so i can answer?
