The answer is:  [B]:  " 15 " .
____________________________________________________
Explanation:
____________________________________________________
"112" and "(7x + 7)" are the measurements of 2 (TWO) vertical angles; 

and all vertical angles are equal;  so, to solve for "x" ; 

       7x + 7 = 112 ;

Subtract "7" from EACH SIDE of the equation:

             7x + 7 - 7 = 112 - 7 ;

to get:  

           7x  = 105  ;

Now, divide EACH SIDE of the equation by "7" ; to isolate "x" on one side of the equation; and to solve for "x" ;

           7x / 7 = 105 / 7 ;

to get:    x = 15 ;   which is:

scoray [572]

Answer:

There was a 1.93% probability of having multiples (twins or more) in 1980.

Step-by-step explanation:

There were 3,612,258 births in the US in 1980.

Of those,

68339 + 1337 = 69676 were multiplies.

So

What was the probability of having multiples (twins or more) in 1980?

P = \frac{69676}{3612258} = 0.0193

There was a 1.93% probability of having multiples (twins or more) in 1980.

Calculate the noon sun angles for new orleans, usa and helsinki, finland on september 22. in the answer below, new orleans answe
Otrada [13]
<span>We need to calculate noon sun angle. Noon sun angle is an angle at which sun-rays fall at noon on a given date.
</span>On September 22, the sun’s rays form a 90° angle at noon at the equator.

Formula for calculating noon sun angle is:

Noon_sun_angle = 90° - Zenith angle

We have complementary angles so we need to substract zenith angle from 90°.

The zenith angle is the distance between subsolar point (point where sun is at 90°) and the latitude of an observer. In our case this angle will have same value as latitude because subsolar point is at equator 0°. If our latitude and subsolar point are at same hemisphere we substract values. Otherwise we add values.

New Orleans, USA
Latitude = 30°
Noon_sun_angle = 90° - 30° = 60°

Helsinki, Finland
Latitude = 60°
Noon_sun_angle = 90° - 60° = 30°
