when running a line, in a right-triangle, from the 90° angle perpendicular to its opposite side, we will end up with three similar triangles, one Small, one Medium and a containing Large one, from where we can use proportions to get their sides, so Check the picture below.

SV−→bisects ∠RST. If m∠RSV = 64, what is m∠RST?

Anuta_ua [19.1K]

Given:

$\overrightarrow{SV}$ bisects ∠RST.

$m\angle RSV=64^\circ$

To find:

The $m\angle RST$ .

Solution:

Since, $\overrightarrow{SV}$ bisects ∠RST, therefore

$m\angle RSV=m\angle VST$ ...(1)

Now,

$m\angle RST=m\angle RSV+m\angle VST$

$m\angle RST=m\angle RSV+m\angle RSV$ [Using (1)]

$m\angle RST=2\times m\angle RSV$

$m\angle RST=2\times 64^\circ$ $[\text{Given }m\angle RSV=64^\circ]$

$m\angle RST=128^\circ$

Therefore, the value of $m\angle RST$ is $128^\circ$ .

Answer:

398,765 books were sold

Step-by-step explanation:

How to get the answer:

1) Identify the given

32,300 is percentage

8.1 % is rate

base (b) is missing

2) Solve

b= p/r

b= 32,300 / 8.1% or 0.081

b= 398,765

3) Check

398,765 x 8.1% = 32,299.97 or 32,300

Carlos Martin received a statement from his bank showing a balance of $56.75 as of March 15. His checkbook shows a balance of $8

Alenkinab [10]

Answer is $22.37:
You subtract $56.75 from $87.37,which equals $30.62, then you add the 2 checks that the bank didn't return and subtract that amount from the $30.62.

Find a of this angle.

Mice21 [21]

In a triangle, the total angle is 180 degrees. A straight line is always 180 degrees. With this in mind, the following can be obtained:

$a + 2x + {57}^{o} = {180}^{o} \\ 5x + a = {180}^{o}$
