We can't tell. We need to know how the angles N and L are related.

It took 48 minutes to drive downtown An app estimated it would be less than that If the error was 20% what was the apps estimate
Zina [86]

Answer:

<em>The app's estimate was 38.4 minutes.</em>

Step-by-step explanation:

Suppose, the app's estimated time was t minutes.

Given that, it took 48 minutes to drive downtown. So, <u>the error in estimated time by the app</u> =(48-t) minutes.

It is also given that the error was 20%. So, <u>the amount of error</u> = (48*0.20)=9.6 minutes.

Thus, the equation will be......

48-t= 9.6\\ \\ -t=9.6-48\\ \\ -t=-38.4\\ \\ t= 38.4

So, the app's estimate was 38.4 minutes.

EB and DA are diameters of circle Y. What is the measure of arc EDC?
Dmitrij [34]

Answer:

Option (D). 110°

Step-by-step explanation:

Since EB and AD are diameter,

m(\widehat{ECB}) = m(\widehat{ACD}) = 180°

m(\widehat{ECB})=m(\widehat{EDC})+m(\widehat{BC}) = 180° -------(1)

And m(\widehat{ACD})=m(\widehat{AB})+m(\widehat{BCD})

180° = 40° + m(\widehat{BCD})

m(\widehat{BCD}) = 140°

Since, m(\widehat{BCD})=m(\widehat{BC})+m(\widehat{CD})

2m(\widehat{BC}) = 140° [Given m(\widehat{BC})=m(\widehat{CD})]

m(\widehat{BC}) = 70°

From equation (1),

m(\widehat{EDC}}) = 180° - m(\widehat{BC})

m(\widehat{EDC}}) = 180°- 70°

Therefore, measure of arc(EDC) = 110°

Option (D) will be the answer.
