See also Tangent to a circle). In any right triangle, the tangent of an angle is the length of the opposite side (O) divided by the length of the adjacent side (A). ... In a formula, it is written simply as 'tan'.
Answer:
C.3
Step-by-step explanation:
SP and SR are tangent to circle Q.
-> SP = SR
-> 10x - 18 = 2x + 6
-> 10x - 2x = 18 + 6
-> 8x = 24
-> x = 24/8
-> x = 3
