Answer:
(2) 72°
Step-by-step explanation:
In this geometry, the angle at the tangent is half the measure of the intercepted arc.
∠CBD = (arc BD)/2 = 144°/2
∠CBD = 72°

<em>Additional comment</em>
Consider a point X anywhere on long arc BD. The inscribed angle at X will have half the measure of short arc BD, so will be 144°/2 = 72°. This is true regardless of the position of X on long arc BD. Now, consider that X might be arbitrarily close to point B. The angle at X is still 72°.
As X approaches B, the chord XB approaches a tangent to the circle at B. Effectively, this tangent geometry is a limiting case of inscribed angle geometry.
Answer:
Yes
Step-by-step explanation:
A statistical question is one that can be asked and expected to receive answers that may vary - in other words, where the data from each participant is different.
Here, the question is "How many times did you ride the Ferris wheel today?” Obviously, it's almost impossible that each person asked rode the Ferris wheel the same number of times. Some people may say "once", others may say "three times", and still others might not have ridden it at all.
Given the differences in all these answers, we can say that this IS a statistical question.
Hope this helps!
Answer:
37800
Step-by-step explanation:
Prime factorization of the numbers:
180 = 2 × 2 × 3 × 3 × 5
189 = 3 × 3 × 3 × 7
600 = 2 × 2 × 2 × 3 × 5 × 5
LCM (180, 189, 600)
= 2 × 2 × 2 × 3 × 3 × 3 × 5 × 5 × 7
= 37800
