Since the angles two and four are vertical they have to equal each other so you put that in an equation and solve for x:
7x+7=140
-7 -7
7x=133 divide both sides by 7
x=19
Since angles 3 and 4 have to equal 180 to make a straight line they have to add together and equal 180 and solve for y:
5y+140=180
-140 -140
5y=40 divide both sides by 5
y=8
So your answer is x=19 and y=8
Domain is all real numbers
The input to an exponential function is the exponent
The base represents the multiplicative rate of change

if 77.28 divided by 4.0 do long division and once you do that check yourself to see if you are correct
I hope I helped you guys! :)
Answer:
the corresponding length can be derived from the actual length by dividing the actual length by 15.
Corresponding length = actual length ÷ 15
x1 = 1/15 × x = x/15
y1 = 1/15 × y = y/15
z1 = 1/15 × z = z/15
Step-by-step explanation:
Let x,y,z represent the actual dimensions of his room.
And x1,y1,z1 represent the corresponding dimensions of his room used in the scale drawing.
Given;
Scale = 1:15
In a scale drawing, the corresponding dimensions uses for the drawing can be derived by multiplying the actual dimensions by the ratio.
Ratio = 1/15
Corresponding dimension = 1/15 × actual dimensions
x1 = 1/15 × x = x/15
y1 = 1/15 × y = y/15
z1 = 1/15 × z = z/15
Therefore the corresponding length can be derived from the actual length by dividing the actual length by 15.
Corresponding length = actual length ÷ 15
