In △ABC, m∠A=16°, m∠B=49°, and a=4. Find c to the nearest tenth.

xenn [34]

Answer:

= 8.33 inches

Step-by-step Explanation

First add 49 + 16, which equals 65, and subtract that result from 180, since a triangle equals 180 degrees and you find out angle C is equal to 115 degrees.

Now using the formula sinA/a = sinB/b = sinC/c, plug in values and you'd get the equation sin49 x 10/sin115. After solving the equation you'd get about 8.32729886047258 inches.

= 8.33

True or False? The graph of sine can be used to construct the graph of the secant function.

amid [387]

True

Note that:

$secant \theta = \frac{1}{cos\theta}$

The graph of sine and cosine functions are very similar. They only have a shift in the x -axis.

That is, sin x = cos (90 - x)

Since there is a great similarity between the sine and cosine graphs, and the secant graph is an inverse of the cosine graph, the graph of sine can be used to construct the graph of the secant function

Mathematically:

since sec x = 1 / cos x

and, cos x = sin (90 - x)

therefore, sec x = 1 / sin (90 - x)

The graphs of the sine and secant functions are attached to this solution
