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
I'm not 100% sure but I believe it's $250
Answer:
Tax credits
State licensing fees
State taxes
Step-by-step explanation:
Tax credits- Usually referred to as a tax deduction. States such as California have an electric car tax credit to encourage transition from carbon-fueled cars to electric or hybrid cars.
State licensing fees-Cars are usually registered in the state in which they are purchased. As such you have to pay the state's licensing fee during car purchase.
State taxes-Different states have different sales tax charged on new, used or leased cars.
Answer:
Last option: 4
Step-by-step explanation:
The quadratic equation simplified: 
has the form:
In this case, you can identify that "a", "b" and "c" are:
To solve this quadratic equation by completing the square, Carlos should add 
to both sides of the equation. This is:
Then:
Therefore you can observe that the number he should add to both sides of the equation is: 4
Answer:
Step-by-step explanation:
So angle 1 and 2 are both obtuse angles. They are considered adjacent angles as well.
Hope this helps
