It's really hard for me to understand what they are asking.​

Mathematics
1 answer:
Gekata [30.6K]2 years ago
3 0

Answer:

B is the correct answer

Step-by-step explanation:

Angles 1, 2, and 3 added together should make 180 degrees.

So, if angle 2 is 70 degrees, you subtract 70 from 180 (180-70=110) and you're left with 110 degrees.

Angle 1 and 3 add together should make 110 degrees which makes B the only true statement.

In circle O, the length of radius OL is 6 cm and the length of arc LM is 6.3 cm. The measure of angle MON is 75°
djyliett [7]

Answer:

14.2cm

Step-by-step explanation:

Complete question:

<em>In circle O, the length of radius OL is 6 cm and the length of arc LM is 6.3 cm. The measure of angle MON is 75°.  </em>

<em>Rounded to the nearest tenth of a centimeter, what is the length of arc LMN?  </em>

<em></em>

Find the diagram attached

arc LN= arc  LM + arc MN

First we need to get the arc MN

length of an arc = theta/360 * 2πr

length of arc MN = 75/360 * 2(3.14)(6)

length of arc MN = 0.20833*37.68

length of arc MN = 7.85

Hence;

arc LN = 6.3 + 7.85

arc LN = 14.15cm

Hence the length of arc LN is 14.2cm
