To copy an angle using only a compass and a straightedge, begin by marking the vertex of the new angle. Then draw a ray from the vertex, which will be one of the legs of the new angle. What is the next step in the construction? A.
Set the compass width to the vertex of the angle, place the compass needle at any point on the leg of the new angle, and make an arc in the angle's interior.
B.
Set the compass to a sufficient width, place the compass needle on one leg of the original angle, and draw an arc on the other leg of the angle.
C.
Set the compass to a convenient width, place the compass needle on one of the legs of the original angle, and draw an arc on the leg of the new angle.
D.
Set the compass to a convenient width, and draw an arc that is centered at the vertex of the original angle and intersects both legs of the original angle.

fa tha first one you gonna add y to both sides

it look like this

x-y+y=6+y

x=y+6

therefore your answer is

x =y+6

fa tha second one

you gonna flip tha equation

it gonna look like x-4y=y

then add 4 to both sides

it gonna look like tha

x-4 +4 =y +4

so therefore tha answer is x=y+4

step-by-step explanation:

a 4/6 = 9/12   not proportional

step-by-step explanation:

to find which are not proportional, we can use cross products

if it is true, they are proportional.   if it is not true, they are not proportional.

a 4/6 = 9/12

4* 12 = 6*9

48 = 54

not this is not proportional  

b 2/3 = 12/18  

2* 18 = 3 * 12

36 = 36

this is proportional

c 5/4 = 10/8  

5*8 = 4*10

40 = 40

this is proportional

d 7/5 = 35/25

7*25 = 5 * 35

175 = 175

is proportional

6(h+1)/2=a

a=area

step-by-step explanation:

its the same thing as a square or rectangle but after multiplying two sides you need to divide it by two.

110

step-by-step explanation:

based on the question i am guessing that it is a typo for abc
