If BC = 7 and CD = 24, find AC.

vodomira [7]

Answer:

2√42 ≈ 12.961

Step-by-step explanation:

All of the right triangles are similar, so ...

short leg/long leg = BC/AC = AC/CD

AC² = BC·CD = 7·24 = 168

AC = √168 = 2√42

Circle T is shown. Angle Q S R intercepts arc Q R. Angle Q S R is 52 degrees. What is the measure of arc Q R? 26° 52° 104° 128°

victus00 [196]

Answer:

104 degrees'

Step-by-step explanation:

Find the diagram attached

According to the theorem;

Angle at the vertex is half the angle at its intercepted arc

Given

Angle at the vertex = 52 degrees

Angle at the intercepted arc = arc QR

Hence;

52 = 1/2 arcQR

Cross multiply

52 * 2 = arcQR

104 = arc QR

Swap

arc QR = 104 degrees'
