Answer:

Two pairs of adjacent angles: (a°&c°) and (c°&b°)

Vertical Angle: (a°&b°)

b°+c°=180° (They lie on the same line, so they are supplementary)

a+b=280°

x+x=280° (Vertically opposite angles are equal. a=b=x)

2x=280°

x=280°/2

x=140°

Now, we now that b+c=180°

140°+c=180° (Put the value of b i.e. b=X=140°)

c=180°-140°

c=40°

One year, the population of a city was 352,000. Several years later it was 337,920.
kvasek [131]

hi

here is  the  method :

you take  Value 1  and Value 2

And you do :   ( Value 2 - Value 1)  / (Value 1 )    * 100

Here we have :    Value 1 = 352 000

                            Value 2 =  337 920

So now we apply :

( 337 920 - 352 000 )  /  ( 352 000)   * 100 =  -4  

Population decreased by by  4 %

You can also make :  

352 000 * X = 337 920

                 X =  337 920 / 352 000

                 X = 0.96

if  the multiplier is  0.96 ,  it's mean that we lost  1 -0.96 = 0.04  

which mean  - 4%

How do you calculate the Hypotenuse?
julia-pushkina [17]
Formula:
a^2+b^2=c^2

c^2: Is the hypotenuse.

For  a^2 and b^2, you have to multiply both it by its self.

Then, add both.

Next, you square root it.

Example:

a^2+b^2=c^2

14^2+7^2=c^2

196+49=c^2

245=c^2

15.64=c^2
