Answer:
17.872, 8
Step-by-step explanation:
Chords that pass through the center are the diameter, and lines that are tangent to the circle are perpendicular to the diameter at that point.
Therefore, what we are looking at are right triangles, and we can find the distance using Pythagorean theorem.
c² = a² + b²
(19.5)² = (7.8)² + b²
b ≈ 17.872
c² = a² + b²
(10)² = (6)² + b²
b = 8
Answer:
the question is not written correctly 16t2 can't be used in the equation
Step-by-step explanation:
do it it correctly you need to combine the like numbers, subtract the 48 from both sides and then divide the number with the t to both sides.
