Dilation creates similar triangles, all the others are isometries, making congruent triangles. Choice a.
Answer:
To find the measure of x you want to put 4x+x equaled to 180, because the measure of a straight line is 180, and 4x and x together make a straight line
Set up your equation:
4x+x=180
Add your like terms
5x=180
Divide by 5 to get x by itself
x=36
Hope this helps ;)
Answer:
Step-by-step explanation:
Let us assume that the total area of the wall to be painted is w.
Then Jason painted an area of (1/4)w on Monday
And he painted (2)(1/4)w on Tuesday
So to find the unpainted area, we just take the whole wall area to be painted (which is w) and subtract out the amounts painted on Monday and Tuesday, which are shown above.
So the unpainted area (U) would be shown by the following expression:
U = w - (1/4)w - (2)(1/4)w
We can simplify this expression by factoring out w
U = w(1 - 1/4 - 1/2)
U = w (1/4) or w/4
So all Jason needs to do is paint as much of the wall as he did on Monday, and he will be done!
Yes that would be correct 0.2 repeating is the decimal form of 2/9
