Answer: Let x=length of the longest side of the smaller triangle.
x/20=3/12
x=60/12
x=5
Cross multiply:-
9 * x = 2 * 8
x = (2 * 8) / 9 = 16/9 or 1 7/9 answer
Hi there!
Since ST is a tangent to the circle, we can use the relationship: tangent squared = external secant segment x entire secant segment.
WORK:
(I will be using x in place of ST)
x^2 = 7(23 + 7)
x^2 = 7(30)
x^2 = 210
x = squareroot(210) or approximately 14.5 inches
Hope this helps!! :)
Answer:
x=5
Step-by-step explanation:
(x - 5)(x - 5) = 0
x-5=0
x=5
