The measure of the supplement of an angle is 20° More than three times the measure of the original angle. Find the measures of t

laiz [17]

Answer:

The measure of the supplement of an angle is 20° More than three times the measure of the original angle. The angles are 40 degrees and 140 degrees.

Solution:

Given, The measure of the supplement of an angle is 20° More than three times the measure of the original angle.

We have to Find the measures of the angles.

Let the original angle be n degrees.

We know that, sum of supplementary angles is 180, then, supplementary angle of n will be 180 – n.

Now according to the given information, 180 – n = 20 + 3 x n

180 – n = 20 + 3n

3n + n = 180 – 20

4n = 160

n = 40

Then, supplementary angle is 180 – 40 = 140 degrees.

Hence, the measures of two supplementary angles are 40 degrees and 140 degrees.

Andy promises opie that he will give him 5000 upon his graduation from college at mayberry u. How much must andy invest today to

san4es73 [151]

Answer: Andy should invest RS. 2784.19 for 12 years .

Step-by-step explanation:

Since we have given that

Amount = Rs. 5000

Time = 12 years

Rate of interest = 5%

So, We need to find the sum:

Using "Compound interest" , we get :

$A=P(1+r)^t\\\\5000=P(1+0.05)^{12}\\\\5000=P(1.05)^{12}\\\\\dfrac{5000}{1.05^{12}}=P\\\\2784.19=P$

Hence, Andy should invest RS. 2784.19 for 12 years .

Square ABCD is located on a coordinate plane. The coordinates for three of the vertices are listed below. ~A(2,7) ~C(8,1) ~D(2,1

Vladimir79 [104]

Answer:

B' (16, 14)

Step-by-step explanation:

Whenever we have a dilation with a scale factor b, we get the new point as:

Let original point be (x,y), then the dilation would make it (bx, by).

There is a diagonal that goes through AC and another through BD. The midpoint of both the diagonal is same. Midpoint formula is:

$(\frac{x_1+x_2}{2},\frac{y_1+y_2}{2})$

Midpoint of AC:

$(\frac{x_1+x_2}{2},\frac{y_1+y_2}{2})\\=(\frac{2+8}{2},\frac{7+1}{2})\\=(5,4)$

Now let vertex B have coordinates (x,y). Midpoint of BD:

$(\frac{x_1+x_2}{2},\frac{y_1+y_2}{2})\\=(\frac{x+2}{2},\frac{y+1}{2})$

Equate this to the midpoint of AC:

(x+2)/2=5

x+2 = 10

x = 8

and

(y+1)/2=4

y+1=8

y = 7

Thus, B(8,7)

recalling dilation of scale factor 2 rule we said at the beginning, B' would be twice of each coordinate. Hence B' = (16,14)
