One of the requirements of a rectangle is that it must have four right angles ( a right angle is 90 degrees) so you just multiply 90 by 4 and you get 360 degrees
Tom will get 166
Ben will get 581
Answer:
![C" = (4,3)](https://tex.z-dn.net/?f=C%22%20%3D%20%284%2C3%29)
Step-by-step explanation:
Given
![C = (3,-4)](https://tex.z-dn.net/?f=C%20%3D%20%283%2C-4%29)
Transformation 1: y = -x reflection
Transformation 2: x axis reflection
Required
The new coordinates of C
![C = (3,-4)](https://tex.z-dn.net/?f=C%20%3D%20%283%2C-4%29)
Transformation 1: y = -x reflection
This gives: (-y,-x)
So:
![C = (3,-4)](https://tex.z-dn.net/?f=C%20%3D%20%283%2C-4%29)
![C' = (4,-3)](https://tex.z-dn.net/?f=C%27%20%3D%20%284%2C-3%29)
![C' = (4,-3)](https://tex.z-dn.net/?f=C%27%20%3D%20%284%2C-3%29)
Transformation 2: x axis reflection
This gives: (x,-y)
So:
![C' = (4,-3)](https://tex.z-dn.net/?f=C%27%20%3D%20%284%2C-3%29)
![C" = (4,3)](https://tex.z-dn.net/?f=C%22%20%3D%20%284%2C3%29)
Answer:
x = 5.5 to the nearest tenth.
Step-by-step explanation:
Here we have a right triangle with one angle (65 degrees) given. Side x is the "side adjacent to the angle" and is to be found. The hypotenuse is 13.
The cosine function makes use of these three knowns: the angle, the hypotenuse and the adjacent side. Thus:
cos 65 degrees = adj / hyp = x / 13, or
x = 13 cos 65
Evaluating this on a calculator, we get x = 5.49, or x = 5.5 to the nearest tenth.
Answer:
5:3:2
Step-by-step explanation:
see image
Jarek gets half. Then from the other half, Jerzy gets 3 pieces of 5 and Justyn gets the leftover 2 pieces. But Jarek's piece is all 5 pieces of the first half.
Jarek 5 parts:
Jerzy 3 parts:
Justyn 2 parts
5:3:2
