Find the measure of Angle R to the nearest tenth. a. 63.8 degrees b. 67.2 degrees c. 70.9 degrees d. 61.5 degrees

Vikki [24]

The complete question in the attached figure

we know that
tan R°=opposite side angle R/adjacent side angle R
opposite side angle R=72 units
adjacent side angle R=25 units
so
tan R°=72/25
R=arc tan (72/25)---------> R=70.85°-------> R=70.9°

the answer is
R=70.9°

Answer:

The function $f(x)= \frac{1}{x^2+2}$ is continuous for all real numbers

Step-by-step explanation:

To know the possible points of discontinuity of this function, we must find out when the denominator of the function is equal to 0.

The denominator is:

$x ^ 2 + 2$

Then we equal 0 and clear x

$x ^ 2 +2 = 0\\\\x ^ 2 = -2$

$x ^ 2> 0$ for any real number.

This means that

$x ^ 2 +2> 0$ <em>for all reals numbers</em>.

Therefore, the function $f(x)= \frac{1}{x^2+2}$ is <em>continuous</em> for all real numbers, that is, it does not have discontinuities.

The graphic of this function is shown in the image
