Question

SD and SG are tangent to ⊙ K. Identify SG. HELP!!

Answer 1

Answer: 63

Tangents drawn from external point to a circle are congruent.

SG = SD

8x - 9 = 5x + 18

8x - 5x = 9 + 18

3x = 27

Step-by-step explanation: 63

Answer 2

63

Explanation:

Tangents drawn from external point to a circle are congruent.

Therefore,

SG = SD

8x - 9 = 5x + 18

8x - 5x = 9 + 18

3x = 27

`x = (27)/(3) \\ x = 9 \\ SG = 8x - 9 \\ SG =8 * 9 - 9\\ SG =72 - 9 \\ \huge \red{ \boxed{SG =63}}`
