Let the center of the given circle is O .

And central angle is double of the angle subtended by the arc.

So central angle is twice of 84 degree.

And twice of 84 is 168 degree.

So the central angle is of measurement 168 degree.

And central angle is the measurement of the arc , therefore measurement of arc QS is 168 degree.

Help me out please.i will give brainly
tankabanditka [31]

Answer:

Hello! answer: 17

Step-by-step explanation:

Assuming this is the Pythagorean theorem our formula would be

a^2 + b^2 = c^2

meaning both of those sides multiplied by themselves added together will equal a number which is the result of c multiplied byitself sorry it sounds confused but...

15 × 15 = 225 8 × 8 = 64 225 + 64 = 289

the square root or the (number multiplied byitself that equals 289) is 17 because

17 × 17 = 289 so × = 17 I hope that helps!

Identify the similar triangles. Find each measure.​
boyakko [2]

Answer:

Example: these two triangles are similar: If two of their angles are equal, then the third angle must also be equal, because angles of a triangle always add to make 180°. So AA could also be called AAA (because when two angles are equal, all three angles must be equal)
