Answer:
180.
Step-by-step explanation:
Given
x = 1%2F2y
x+y=180
...
Substitute x into the second equation and solve for y, the larger angle
1%2F2y + y = 180
Multiply both sides by 2 to be rid of the fraction
y + 2y = 360
3y = 360
highlight_green%28y=120%29

Answer:
10
Step-by-step explanation:
32 - 12 (because C is 12 years younger) = 20
20 / 2 (because <em>twice</em> Anna's age, so we do the inverse) = 10
Anna is 10 years old.
Hope this helps!
Don't you mean "coords," or (better yet) "coordinates?"
Look at line DG as an example. It's vertical. If you rotate the whole figure clockwise, then line DG becomes the horiz. line D'G.' G' would have the coordinates (-1,-1), and D' (5,-1). Plot these points G' and D' and see whether or not you agree.
1/10 of a mile. 4/5 is equivalent to .8, and dividing that by 8 would give you .1, and that is equivalent to 1/10.
