Answer:

r = 10

Step-by-step explanation:

The equation of a circle centred at the origin is

x² + y² = r² ( r is the radius )

x² + y² = 100 ← is a circle centred at the origin with

r² = 100 ( take the square root of both sides )

r = \sqrt{100} = 10

You would convert 17 1/4 to 17 4/16, and change 7/8 to 14/16. Then you would add those 2 numbers together to get 17 18/16 or simplified, 18 1/8.

I need help with 5-6 PLEASEEEE!! Also please excuse the answers cause I know it’s wrong
sergey [27]

Step-by-step explanation:

5.

angle STQ is the supplementary angle (together they are 180° below line MQ) to 2x + 8.

above ST we have a group of 3 angles that combine to 180° :

2x + 8

90°

71 - x

so, to get x first :

2x + 8 + 90 + 71 - x = 180

x + 169 = 180

x = 11

so, the angle MTS =

2x + 8 = 2×11 + 8 = 22 + 8 = 30°.

6.

therefore, the angle STQ is

180 - angle MTS = 180 - 30 = 150°.

x =  \sqrt{ { \sqrt{18} }^{2} +  {2}^{2}  }  =  \sqrt{18 + 4}  =  \sqrt{22}  \\ y =  \sqrt{ { \sqrt{18} }^{2}  +  {9}^{2} }  =  \sqrt{18 + 81}  =  \sqrt{99}  =  3\sqrt{11}
