Aquadrilateral pqrs is inscribed in a circle, as shown below
what is the measure of arc pqr?
190
265
275
340

Option A is correct.

The measure of Arc PQR is 190 degree

Step-by-step explanation:

Given a cyclic quadrilateral PQRS is inscribed in a circle as shown in figure.

Given:

An intercepted arc measures twice the intercepted angle.

The intercepted angle in the given figure is Arc PQR =                    ......[1]

First find the ;

A quadrilateral is cyclic if and only if opposite angles sum to 180°.

then;

Substitute the value of in above equation we get;

Simplify:

Now; to find the measure of arc PQR ;

[1] ⇒ Arc PQR = =

Therefore, the measure of arc PQR is 190 degree.

since the airplane is moving with constant speed then the distance travelled can be calculated by x=u*t

in km/h would be:

x=640*3.5=2.240 km

in m/s would be:

u=640 km/h= 640.000 m/h =640.000/ 3600 m/s =177.8 m/s

t= 3.5 h= 3.5 * 3600 s=12.600 s

then x=u*t= 177.8*12.600= 2.240.280 m

there is nothing below so i cannot
