Answer:

z would equal 20°

Step-by-step explanation:

This means ACB and EFD are 2 similar triangles

They have the same shape but different size

In ACB because 3 corner of a traingle must = 180° so in this case, corner BAC would = 180 - 65 - 55 = 60°

As you can see, BC is 3 times as large as DF, this means triangle ACB is larger than triangle EFD 3 times, this would lead to corner BAC is larger than corner DEF 3 times.

Corner DEF would = corner BAC / 3

= 60° / 3

= 20°

SO z would equal 20°

Hope this helped :3

Answer:

z = 60°

Step-by-step explanation:

Since the triangles are similar the corresponding angles are congruent, thus

∠E = ∠A

The sum of the 3 angles in a triangle = 180°

Sum the 2 given angles in ΔABC and subtract from 180 for ∠A

65 + 55 + ∠A = 180

120 + ∠A = 180 ( subtract 120 from both sides )

∠A = 60°, hence

z = ∠A = 60°

Solve for x parallel ​
umka2103 [35]

Answer:

x=5

Step-by-step explanation:

Hi there! So when it comes to these two angles, you have to set them equal to each other. From there, you have to isolate the x values, so I subtracted x from the 3x and added 15 to the -5. If you plug in the 5 for the x values, both give the value of 0, so it all checks out. I hope this helped! Please mark this as brainliest if I managed to get this correct. <3

Find the accumulated amount of the annuity. (Round your answer to the nearest cent.) $1000 monthly at 4.6% for 20 years.
pantera1 [17]

Answer:

Accumulated amount will be $2504.90.

Step-by-step explanation:

Formula that represents the accumulated amount after t years is

A = A_{0}(1+\frac{r}{n})^{nt}

Where A = Accumulated amount

A_{0} = Initial amount

r = rate of interest

n = number of times initial amount compounded in a year

t = duration of investment in years

Now the values given in this question are

A_{0} = $1000

n = 12

r = 4.6% = 0.046

t = 20 years

By putting values in the formula

A = 1000(1+\frac{0.046}{12})^{240}

  = 1000(1+0.003833)^{240}

  = 1000(1.003833)^{240}

  = 1000×2.50488

  = 2504.88 ≈ $2504.90

Therefore, accumulated amount will be $2504.90.

The answer is infinite solutions, but what would I put in the circled box?
dusya [7]

Answer:

  x = 10 - 2y

Step-by-step explanation:

The question is telling you to express x in terms of y. Essentially, you solve the given equation(s) for x.

x can be found from the first equation by subtracting 2y from both sides:

  x = 10 - 2y

_____

When there are infinitely many solutions, either x or y can be arbitrarily chosen, and the appropriate value computed for the other variable.

Here, the answer is telling you "type an expression using y as the variable as needed." That is, y is selected to be the variable arbitrarily chosen, and we need an expression that will tell us the corresponding value of x. The appropriate expression is found by rearranging the equation(s) to "make x the subject". (I call that process "solve the equation for x.")
