No
No this is not a triangle because two lengths cannot equal the third.
5/3 % * x = 4.75
5/300 x =4.75
x = 4.75 * 300/5
x=4.75 * 60
x=285
0.002 meters or 2 times 10^-3
You haven't add the choices to be selected. Anyway, some of them I know which are necessary to describe a rotation of a figure on a coordinate plane.
The center of rotation
The number on of degrees of the rotation The direction of the rotation
1.) 3.06 x10^13
2.) 3.199996 x10^12
3.) 7.75 x10^7
