Answer:

AB = 5cm

AC = 12cm

BC = 13cm

A = 90 deg

B= arctan(AC/AB)=arctan(12/5) =67.38 deg

C=arctan(AB/AC) =arctan(5/12) = 22.62 deg

Plz I need help as soon as you see this... and I need the work so I understand it plz!​
poizon [28]

Answer:

8. Obtuse

11. Obtuse

Step-by-step explanation:

c^2 = a^2 + b^2

for 8, it's 6 squared plus 9 squared, which is 117. now, 15 squared is 225. 225 is bigger than 117, which makes it obtuse. if the two results equaled each other, it would be a right triangle. if the 2 smaller numbers when squared were bigger than the hypotenuse squared, then it would be acute

What are the coordinates of the image rectangle for a scale factor of 3 if the center of dilation is the origin?
Ksju [112]

Answer: Choice B)

Explanation:

You mentioned there isn't a diagram to go with this, but I'm assuming that this problem is referring to a previous problem you posted. In that problem, it mentions that point W is at (1,-2). If we apply the scale factor 3, then we're tripling each coordinate. That means x = 1 becomes x = 3, and y = -2 becomes y = -6

We can write it like this:

(1,-2) ---> 3*(1, -2) = (3*1, 3*(-2) ) = (3, -6)

Only choice B has W'(3,-6) so this is likely the final answer.

If we apply this dilation to every point, then that effectively makes quadrilateral W'X'Y'Z' to be three times longer and taller than compared to quadrilateral WXYZ. In other words, its side lengths are 3 times longer.
