Answer:

BC = 6

CA = 6

Step-by-step explanation:

In an equilateral triangle all measures of side are equal.

Therefore,

AB = BC = CA = 6

Andrea is given AABC and told that a² + b2 = c2. She draws right triangle RTS with legs
Vinvika [58]

Question:

Andrea is given AABC and told that a² + b2 = c2. She draws right triangle RTS with legs

measuring a and b and hypotenuse measuring 2. Which best describes what Andred should

do in order to prove that AABC is a right triangle?

1) Show that a² + b2 = c2, so ZA ZR. This means AABC = ARTS, and so ZC is a right angle

and so AABC is a right triangle.

2) Show that c = 2, so AABC = ARTS and so ZC = ZS. This means ZC is a right angle, and so

AABC is a right triangle.

3) Show that c = x, so AABC = ARTS and so ZCZ ZS. This means ZC is a right angle, and so

ABC is a right triangle.

O

4) Show that c = r, so AABC ~ ARTS and so ZC ~ ZS. This means ZC is a right angle, and so

AABC is a right triangle.

Answer:

The correct option is;

2) Andrea should show that c = 2 so ∡ABC = ∡RTS and ∡C = ∡S hence ∡C is a right angled triangle hence ΔABC is a right triangle

Step-by-step explanation:

Here, we have that the given sides of the triangle are a, b and c and therefore, whereby Andrea is able to draw the two sides of the right triangle with sides = a and b and the third, hypotenuse, side as equal to 2, we know that since the length of the hypotenuse = 2, then we have;

2² = a² + b²

However, we are told that c² = a² + b²

Therefore, c = 2 hence, Andrea should show that c = 2 so ΔABC = ΔRTS and ∡C = ∡S hence ∡C is a right angled triangle since it is the angle opposite to the hypotenuse c and therefore, ΔABC is a right triangle.

Your annual salary is $28,460 your State personal deductions total $88 for a weekly pay period. The state tax rate is 3.6% of ta
miv72 [106K]

Answer:

First, in one year you win:

$28,460

Now yearly we can subtract:

3.6% for the taxable income

1.7% for the gross pay:

(Those apply to the complete annual salary)

3.6% + 1.7% = 5.3%

This in decimal notation is 0.053, then paying those two things we have left:

$28,460*(1 - 0.053) = $26,951.62

Now we need to subtract the union dues, which are $156 per year.

$26,951.62 - $156 = $26,795.62

Now, this is yearly, and we want to know the weekly pay.

In one year we have 365 days.

One week has 7 days.

Then in one year, we have:

365/7 = 52.14 weeks.

Then the pay per week is:

$26,795.62/52.14 = $513.92

And now, each week we must pay $88 for state personal deductions, and $67 for FIT.

Then we have:

$513.92 - $88 - $67 = $358.92

Then the net pay for each weekly pay period is: $358.92

Can anyone help ? I’m bad at math
Reil [10]

Answer:

Step-by-step explanation:

First you need the third angle (C).

<C + 89  + 45 = 180       All triangles = 180 degrees. Combine the left terms.

<C + 134 = 180               Subtract 134 from both sides

<C = 180 - 134

<C = 46

Next, Let BA = x

x/Sin(46) = 15/Sin(89)

x = 15*sin(46) / Sin(89)

Sin(46) = 0.7193

Sin(89) = 0.9998

x = 0.7193 * 15 / 0.9998

x = 10.7911

Note

When you are studying this material, you should note 2 things.

  • The first is that you are dealing with 2 ratios that are equal to each other.
  • The second is, the side is always opposite the angle in the triangle. The two are connect. Side c = 15. It is opposite the 89o angle.

Step-by-step explanation:

Let the monthly rent be x.

<u>Then we have:</u>

  • x + 0.5x + 0.4x = 3800
  • 1.9x = 3800
  • x = 3800/1.9
  • x = 2000

Monthly rent is $2000

What is the value of ​2×[34−5×(3+1)]​ ?
spayn [35]

Answer:

\boxed{ \bold{ \huge{ \boxed{ \sf{28}}}}}

Step-by-step explanation:

Use BODMAS rule :

Bracket , Of , Division , Multiplication , Addition , Subtraction

\sf{2 \times [ 34 - 5 \times (3 + 1) ] }

Add the numbers : 3 and 1

\dashrightarrow{ \sf{2 \times [ 34 - 5 \times 4 ] }}

Multiply the numbers : 5 and 4

\dashrightarrow{ \sf{2 \times [ 34  - 20 \: ]  }}

Subtract 20 from 34

\dashrightarrow{ \sf{2 \times 14}}

Multiply the numbers : 2 and 14

\dashrightarrow{ \sf{28}}

Hope I helped!

Best regards! :D
