Answer:

< F , < E, < D

Step-by-step explanation:

ΔDEF

Arrange the sides from smallest to largest

DE = 4, FD = 13, and EF = 15.

Largest side opposes the largest angle, medium side opposes the medium angle, smallest side opposes the smallest angle.

the angles of ΔDEF in order from smallest to largest

Find the radian measure of the central angle

Scorpion4ik [409]

The radian measure of central angle is 0.8 radians

Solution:

Given that we have to find the radian measure of central angle

From given figure in question,

Arc length = 60 units

Radius = 75 units

$\theta = ?$

The radian measure of a central angle θ of a circle is given as:

$s = r \times \theta\\\\\theta = \frac{s}{r}$

Where,

"r" is the radius of circle

"s" is the length of arc

$\theta$ = central angle in radians

Substituting the known values,

$\theta = \frac{60}{75} = 0.8$

Thus radian measure of central angle is 0.8 radians
