Answer:
m∠K = 69°
Step-by-step explanation:
"When two tangents or secants intersect outside the circle, exterior angle formed between the tangents of secants is one half the difference of major and minor arcs"
By this theorem,
m(∠K) = ![\frac{1}{2}[m(\widehat{LBJ}-m(\widehat{LJ})]](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B2%7D%5Bm%28%5Cwidehat%7BLBJ%7D-m%28%5Cwidehat%7BLJ%7D%29%5D)
Here,
= 249°
= 360° - 249°
= 111°
m∠K = 
= 
= 69°
Therefore, measure of angle K = 69° will be the answer.
Answer:
52 and 417
Step-by-step explanation:
A constant means a fixed value which can never vary.
So 417 and 52 are numbers which are fixed to be like that.
Answer:
Mean travel time = 10.33 minutes
Step-by-step explanation:
The mean of a distribution is a measure of central tendency that shows the centre of a set of data. Mathematically, it is represented as:
Mean = Sum of the terms ÷ Number of terms
Mean = (10 + 13 + 16 + 5 + 4 + 14) ÷ 6
Mean = 62 ÷ 6 = 10.33
∴ Mean travel time = 10.33 minutes
N:B 10.33 minutes = 10 minutes + 0.33 minutes
converting 0.33 minutes to seconds
1 minute = 60 seconds
∴ 0.33 minute = 60 × 0.33 = 19.8 seconds
∴ Mean time = 10 minutes 20 seconds
