Answer:
x = 37
Step-by-step explanation:
i just check it with a protractor, if 37 is the answer then that means " (4x - 20) degrees" is 143.
143 + 37 = 180
i think the answer is probably x = 37
Answer:
Step-by-step explanation:
step 1
Find the measure of arc PK
we know that
The measure of the inner angle is the semi-sum of the arcs comprising it and its opposite.
Let
x------> the measure of arc IV
y ------> the measure of arc PK
substitute the values and solve for y
The measure of arc PK is 
step 2
Find the measure of angle VPL
we know that
The inscribed angle measures half that of the arc comprising
Let
z------> the measure of arc VK
y ------> the measure of arc PK
substitute the values
A) Olaf has 250 files, which represent 100%. 12% of that are photos which number is unknown (x).
250 files - 100%
x photos - 12%
So, the proportion should look like:
250 files : 100% = x : 12%
B) After crossing the products:
x = 250 files * 12% : 100%
x = 30 photos
Hello,
First of all,
C. and D. are both incorrect because they apply translations to ABC; translations will misalign ADE with ABC.
Next,
A. is incorrect because a dilation of 1/2 will place D at (0,3) from its original point of (0,2). Also, the dilation will place E at (6,0) from its original point of (4,0). The triangle ADE would be too small to map ABC.
Finally,
B. Is the correct answer because a dilation of 2 will place D at (0,4)—where B is—and will place E at (8,0), where C is.
Choice B. maps ADE onto ABC
Sorry for that much information, but I think it’s useful. XD
Y=-1/4x+7.5 is the right equation
