Find each measurement indicated round your answers to the nearest tenth. Part 1d. NO LINKS OR ANSWERING QUESTIONS YOU DON'T KNOW
valkas [14]

Answer:

see explanation

Step-by-step explanation:

Using the Sine rule in all 3 questions

(1)

\frac{a}{sinA} = \frac{b}{sinB} , substitute values , firstly calculating ∠ B

[ ∠ B = 180° - (78 + 49)° = 180° - 127° = 53° ]

\frac{a}{sin78} = \frac{18}{sin53} ( cross- multiply )

a sin53° = 18 sin78° ( divide both sides by sin53° )

a = \frac{18sin78}{sin53} ≈ 22.0 ( to the nearest tenth )

(3)

\frac{c}{sinC} = \frac{a}{sinA} , substitute values

\frac{35}{sinC} = \frac{45}{sin134} ( cross- multiply )

45 sinC = 35 sin134° ( divide both sides by 35 )

sinC = \frac{35sin134}{45} , then

∠ C = sin^{-1} ( \frac{35sin134}{45} ) ≈ 34.0° ( to the nearest tenth )

(5)

Calculate the measure of ∠ B

∠ B = 180° - (38 + 92)° = 180° - 130° = 50°

\frac{a}{sinA} = \frac{b}{sinB} , substitute values

\frac{BC}{sin38} = \frac{10}{sin50} ( cross- multiply )

BC sin50° = 10 sin38° ( divide both sides by sin50° )

BC = \frac{10sin38}{sin50} ≈ 8.0 ( to the nearest tenth )

What is the exact value of BC?<br>A. 3.16<br>B. 5\|2<br>C. 7.07<br>D. 25<br>​
Natalija [7]

Answer:

C. \:  \:  7.07

Step-by-step explanation:

Coordinates of B are

(5,5)

Coordinates of C are

(4, - 2)

Distance between two points

\sqrt{({x_2 - x _1 {)}^{2} + (y_2 - y_1 {)}^{2} }}

Distance of BC

\sqrt{(4 - 5) {}^{2} + (  - 2   - 5 {)}^{2}  }

\sqrt{ { (- 1}^{2})  +  ({ - 7}^{2}) }

\sqrt{1 +49 }

\sqrt{50}

7.07

Elijah just bought a house with a $72,000 mortgage at a 3.13% annual interest rate. How much of a $930 payment will go towards p
Mamont248 [21]

Answer: $742.20

Step-by-step explanation:

The payments will be divided between an interest and a principal payment.

The interest payment will be based on the balance at the beginning of the period and the rest of the payment will be the mortgage.

Balance at beginning of period = $72,000

Interest payment = (3.13% * 72,000) / 12 months

= $187.80

Amount going towards principal:

= Total payment - Interest payment

= 930 - 187.80

= $742.20
