Check the picture below
in case you want to know how to get who's the adjacent or opposite, notice in the picture, if you put your eye on the angle itself, what you'd be facing is the opposite side, the adjacent is the side touching the angle.
BD = 2x-4
But it's also BE - CE + CD
BE is 3x-1
CE is 2x-3
CD is 2
so
BD = 3x-1 -(2x-3) +2
simplified
BD = 1x +4
since BD = BD (obviously), we can also say that the righthand sides of the two equation must be equal
2x -4 = 1x +4
let's solve for x and that put it into either of the 2 equations.
2x -4 = 1x +4
subtract 1x on both sides
x -4 = 4
add 4 on both sides
x = 8
substitute x for its value in 2x -4 = 1x +4
(this way we double check BD in two expressions at once. the equation should come out true, meaning same value for BD in each expression. both sides should be equal).
2*8 -4 = 1*8 +4
12 = 12
seems true
BD is safely 12
20 didn't do it for this one.
Answer:
The transformation in this figure is rotation.
Step-by-step explanation:
The transformation in this figure is rotation.
There are four types of transformation.
<u>Translation:</u>
Movement of the object without rotating it or changing its size.
<u>Reflection:</u>
Flipping the object about a line of reflection. The mirror image is formed after transformation.
<u>Dilation:</u>
Changing the size of a figure without changing its essential shape.
<u>Rotation:</u>
A rotation is a transformation that turns a figure about a fixed point called the center of rotation.An object and its rotation are the same shape and size, but the figures may be turned in different directions....
