After reading through the story problem, I ended up with this equation:
(35-2)(x+.5) =?
or
(35-2)(10+.5)=?
Explanation:
He sells 35 books for usual weeks. Since he is selling his books at $.50 more his average number of copies decreased by 2.
35-2 = 33
Next, we know that he adds $.50 for his price for each copy. If the price is $10 per copy than it looks like this:
$10+$.50= 10+.5
or if the price is not $10 it will be
$x+$.5= x+.5
To find the values of x and y, you do this:
In the figure there are 3 different triangles made up. So lets start with the big one in the middle.
As you may already know, all 3 angles of a triangle add up to 180. And you already know 2 of the angles which are 35 and 30. When added together it is 65. so to find the last angle, you subtract 65 from 180. and that equals 115. so the last angle in that triangle is 115 degrees.
Now you already know all the angles of 1 triangle so lets go to the next step.
Next to the angle we just found there 2 other angles on either side of it. And they are supplementary to the angle we just found. And supplementary angles are 2 angles that add up to 180 degrees. And since we already know that that angle is 115, we just have to subtract that from 180. and that equals 65. So both of those angles equal 65. And if you dont know, they both equal the same because they are vertical angles and vertical angles always equal the same amount.
Now we know 2 angles of both the side triangles. We have the 65 that we just found, and since their right angles we have 90. So 65 and 90 add up to 155. And 155 subtracted from 180 equals 25. And 25 is the measure of the last angles wich are x and y.
So the values of X and Y are 25 degrees.
Answer:
66°{B}
Step-by-step explanation:
30°+57°+27°+x=180°
114°+x=180
x=180°-144°
66°

true.

The GCF of two numbers is the largest number that <u>divides evenly</u> into both numbers. If both numbers are even, this means 2 will be part of the GCF, which will make the GCF even.</span></span>
Given that the triangle ABC is dilated by a scale factor of 1.25 to form the new triangle PQR, the dimensions of PQR will be as follows;
AB corresponds to PQ, but the length of AB=5 units, the length of PQ will be:
PQ=5*1.25=6.25 units
BC corresponds to QR, but the length if QR=4.2 units, the length of QR will be:
QR=4.2*1.25=5.25 units
lastly,
CA corresponds to RP, but CA=4 units, therefore RP will be:
4*1.25=5 units
