Answer:


Step-by-step explanation:

Nice summary problem.

<AEC

  • AEC = 360 - 243.5 = 116.5    
  • The number of degrees in 1 rotation of a circle = 360o. You have accounted for 243.5 degrees. What is left over is the answer.

<EAD and <ECD

Both of these are tangents to a circle. Tangents meet radii at 90 degree angles.

<EAD = <ECD = 90 degrees

<ABC

<ABC is 1/2 the central angle. The Central angle is <AEC

  • < AEC = 116.5
  • <ABC = 1/2 * 116.5
  • <ABC = 58.25

<ADC

There are 2 ways of doing this. You should know both of them.

<em><u>One</u></em>

All quadrilaterals = 360 degrees. You know three of the angles. You should be able to find ADC

  • <ADC + 90 + 90 + 116.5 = 360     Add the four angles together.
  • <ADC + 296.5 = 360                   Combine terms on the left
  • <ADC = 360 - 296.5                    Subtract 238.25 from both sides
  • <ADC = 63.5                                 Answer

<em><u>Method Two</u></em>

<ADC = 1/2 (major Arc - Minor Arc)  This formula is fundamental to circle / tangent properties. The Major arc is the larger of the two parts of the circumference of a circle. The Minor arc is the smaller.

  • <ADC = 1/2(243.5 - 116.5)
  • <ADC = 1/2(127)
  • <ADC = 63.5

Levart [38]

Answer:

x>=0

Step-by-step explanation:

From the equation, we can see that x must be greater or equal to 0. This is true because every answer to an absolute value is positive or equal to 0. That is your answer.

for a certain year, the combined revenues for PepsiCo and coca-cila were $51 billion. If the revenue for PepsiCo was $9billiin m
BlackZzzverrR [31]
So if the combined revenues were $51 billion. Then it would be best to divide that between the two companies as a starting point. Each company would have $25.5 billion if they were split 50-50. Since PepsiCo has 9 billion more than Coca-Cola. Simply take PepsiCo's value and add $9 billion to it, which would be $34.5 billion. Finally, take $51 billion, subtract it $34.5 billion, which is PepsiCo's value to get Coca-Cola's value, which is 16.5 billion for me.
