Which of the following segments is a radius of OK?<br> ОА. АМТ<br> ОВ. Вт<br> Ос. AMR<br> O D. KM
FrozenT [24]

Answer:

A) TA

Step-by-step explanation:

A radius goes from the center of a circle to the outside edge.  

RP connects two points on the outside edge of the circle without going through the center.  This is not a radius.

TR connects two opposite points on the outside edge of the circle while going through the center.  This is a diameter, not a radius.

GP connects two opposite points on the outside edge of the circle while going through the center.  This is a diameter, not a radius.

TA connects the center of the circle to the outside edge.  This is a radius.

The ratio of two numbers that add up to 180 is 2:8.find the two numbers
aksik [14]

Answer:

36 and 144

Step-by-step explanation:

Sum the parts of the ratio, 2 + 8 = 10 parts

Divide the sum of the 2 numbers by 10 to find the value of one part of the ratio.

180 ÷ 10 = 18 ← value of 1 part of the ratio, thus

2 parts = 2 × 18 = 36

8 parts = 8 × 18 = 144

Thus 2 numbers are 36 and 144
