Answer: (\frac{1080}{11})^{\circ} and (\frac{900}{11} )^{\circ}

Step-by-step explanation:

Here, the ratio of the angles formed by diagonals and the sides of the rhombus is 6:5.

Let the angles formed by diagonals and the sides of the rhombus are 6x and 5x.

Where x is any number.

Therefore, the angles of rhombus are = 12 x and 10x ( Because in rhombus opposite angles are equal and diagonals are the angle bisectors in case of rhombus)

Also, In rhombus diagonals bisect each other perpendicularly.

6x + 5x + 90^{\circ} = 180^{\circ}

\implies 11 x + 90^{\circ} = 180^{\circ}

\implies 11x = 90^{\circ}

\implies x = \frac{90}{11}

⇒ The one angle of rhombus = (6\times \frac{90}{11})^{\circ}=(\frac{540}{11})^{\circ}    

And another angle = (5\times \frac{90}{11})^{\circ}=(\frac{450}{11})^{\circ}

The value of x satisfying both the equations 4x – 5 = y and 2x – y = 3, when y = -1 is
schepotkina [342]

Answer:

x = 1

Step-by-step explanation:

4x-5=y

4x-5= -1

4x = -1+5

4x=4

x=1

2x-y=3

2x-(-1)=3

2x+1=3

2x= 3-1

2x= 2

x=1

since the two answers for x are the same therefore:

x = 1

4(x)+6+3=17 what does x equal
gogolik [260]

Hello There!

X=2

To solve this, we first need to understand that when we see an X in parentheses, we multiply the number before it in this case 4 by X.

The answer is 2 because we multiply 4 by 2 which is the x value so 4*2 is equal to 8 and they we add 9 to it because the sum of 6 and 3 is 9.

Finally, our answer we get is 17 so our X value is 2.

Have A Great Day!

As a graduating senior, Chun Kumora of Manhattan, Kansas, is eager to enter the job market at an anticipated annual salary of $4
ludmilkaskok [199]

1. Chun Kumora's salary after 11 years will be <u>$63,117.6200</u>.

2. Chun Kumora's salary after 21 years will be <u>$93,429.4900</u>.

3. Chun must receive raise greater than <u>$42,640</u> ($41,000 x 1.04) for the next year and greater than <u>$44,345.6000</u> ($42,640 x 1.04) for the year after.

<h3>How are the future salaries determined?</h3>

The future salaries (values) can be determined using an online finance calculator that compounds with the sum of the average inflation rate of 2% and the cost-of-living raise of 2% for 11 and 21 years, respectively.

<h3>Data and Calculations:</h3>

Future Value in 11 years:

N (# of periods) = 11 years

I/Y (Interest per year) = 4% (2% x 2)

PV (Present Value) = $41,000

PMT (Periodic Payment) = $0

<u>Results</u>:

FV = $63,117.62 ($41,000 + $22,117.62)

Total Interest = $22,117.62

<h3>Future Value in 21 years:</h3>

N (# of periods) = 21 years

I/Y (Interest per year) = 4% (2% x 2)

PV (Present Value) = $41,000

PMT (Periodic Payment) = $0

<u>Results</u>:

FV = $93,429.49 ($41,000 + $52,429.49)

Total Interest = $52,429.49
