Find the exact value of s in the given interval that has the given circular function value.

docker41 [41]

Answer:

$\displaystyle s=\frac{3\pi}{4}$

Step-by-step explanation:

Trigonometric Values

We need to find the angle s in the interval [π/2,π] where:

$\displaystyle \sin s=\frac{\sqrt{2}}{2}$

There are two possible angles that have the same sine value in the first rotation of s. Any angle on the first quadrant has the same sine as its supplementary angle in the second quadrant.

The first angle s whose sine is $\frac{\sqrt{2}}{2}$ is:

$\displaystyle s=\frac{\pi }{4}$

The other angle is its supplementary angle:

$\displaystyle s=\pi-\frac{\pi }{4}=\frac{3\pi}{4}$

Only this last angle lies on the required interval, thus:

$\boxed{\displaystyle s=\frac{3\pi}{4}}$

For a circle of radius 5 feet, find the arc length s subtended by a central angle of 42 degress

MrMuchimi

$\bf \textit{arc's length}\\\\
s=\cfrac{\theta r\pi }{180}\quad 
\begin{cases}
r=radius\\
\theta = angle~in\\
\qquad degrees\\
------\\
r=5\\
\theta = 42
\end{cases}\implies s=\cfrac{42\cdot 5\cdot \pi }{180}$

In ΔXYZ, ∠Y is a right angle and sin X = 12/25 Find sec X, tan X, and cos Z in fraction and in decimal form. Round to the neares

Bezzdna [24]

Answer:

In ΔXYZ

∠Y is a right angle
∠X and ∠Z are complementary angles
sin X = 12/25

-------------

sec X = 1/cos X = $1/\sqrt{1- sin^2X} = 1/\sqrt{1 - 12^2/25^2} = 1/\sqrt{481}/25 = 25/\sqrt{481}$
tan X = sin X / cos X = $12/{25 : {\sqrt{481} }/25 = 12/{\sqrt{481} }$
cos Z = sin X = 12/25
