Bisectors of angles A, B and C of a triangle ABC intersect its circumcircle at D, E and F respectively. Prove that the angles of

Simora [160]

Answer:

The region between a chord and either of its arcs is called a segment the circle.

Angles in the same segment of a circle are equal.

Step-by-step explanation:

Let bisectors of angles A, B and C of a triangle ABC intersect its circumcircle at D, E and F .

Now from figure,

∠D = ∠EDF

∠D = ∠EDA + ∠ADF

Since ∠EDA and ∠EBA are the angles in the same segment of the circle.

So ∠EDA = ∠EBA

Hence ∠D = ∠EBA + ∠FCA

Again ∠ADF and ∠FCA are the angles in the same segment of the circle.

hence ∠ADF = ∠FCA

Again since BE is the internal bisector of ∠B and CF is the internal bisector of ∠C

So ∠D = ∠B/2 + ∠C/2

Similarly

∠E = ∠C/2 + ∠A/2

and

∠F = ∠A/2 + ∠B/2

Now ∠D = ∠B/2 + ∠C/2

=∠D = (180 - ∠A)/2

(∠A + ∠B + ∠C = 180)

∠D = 90 - ∠A/2

∠E = (180 - ∠B)/2

∠E = 90 - ∠B/2

and ∠F = (180 - ∠C)/2

∠F = 90 - ∠C/2

Jill has a balance of $5,000 on one credit card with an annual interest rate of 10%. To pay of the $5,000 in three years, Jill w

masha68 [24]

Answer:

<u>Jill has to pay US$ 413.64 in addition when the interest rate changes from 5% to 10% on the US$ 5,000 balance</u>

Step-by-step explanation:

1. Let's review the information given to us to answer the question correctly:

Minimum monthly payment Jill have to make to pay the balance of US$ 5,000 with an annual interest rate of 10% = US$ 161.34

Minimum monthly payment Jill have to make to pay the balance of US$ 5,000 with an annual interest rate of 5% = US$ 149.85

Time it takes pay totally the US$ 5,000 on both credit cards = 3 years

2. How much more does Jill have to pay when the interest rate changes from 5% to 10% on the $5,000 balance?

To find the difference between the two credit cards monthly payments, we make this calculation:

Difference = Minimum monthly payment Jill have to make to pay the balance of US$ 5,000 with an annual interest rate of 10% - Minimum monthly payment Jill have to make to pay the balance of US$ 5,000 with an annual interest rate of 5%

Difference = 161.34 - 149.85

Difference = US$ 11.49 per month

Now, for calculating how much more Jill has to pay when the interest rate changes from 5% to 10% on the US$ 5,000 balance, we use this multiplication:

Monthly difference * 3 years = monthly difference * 36 months

= 11.49 * 36 = 413.64

<u>Jill has to pay US$ 413.64 in addition when the interest rate changes from 5% to 10% on the US$ 5,000 balance</u>
