Answer:
m∠7 = 63 degrees
m∠8 = 117 degrees
m∠9 = 63 degrees
Step-by-step explanation:
When two lines intersect at a point, then they formed 2 pairs of vertically opposite angles and 4 pairs of linear angles
- The vertically opposite angles are equal in measures
- The linear angles have a sum of 180°
In the given figure
∵ There are two lines intersected at a point
∴ The angle of measure 117° and ∠8 are vertically opposite angles
∴ ∠7 and ∠9 are vertically opposite angles
∴ The angle of measure 117° and ∠7 are linear angles
∵ The vertically opposite angles are equal in measures
∴ The angle of measure 117° and ∠8 are equal in measures
∴ m∠8 = 117°
∵ The sum of the measures of the linear angles is 180°
∴ m∠7 + 117° = 180°
→ Subtract 118 from both sides
∵ m∠7 + 117 - 117 = 180 - 117
∴ m∠7 = 63°
∵ m∠7 = m∠9 ⇒ proved up
∴ m∠9 = 63°

Answer:
   180 miles
Step-by-step explanation:
Don drove (50 mi/h)×(2 h) = 100 mi.
Frank drove (40 mi/h)×(2 h) = 80 mi.
Since they drove in opposite directions, the total distance between them is 
   100 mi +80 mi = 180 mi.
 
        
             
        
        
        
A., because to find LCD, you must find the LCM of the three denominators. In this case, one of the denominators has the answer, which is 16, because 2, 8, and obviously 16 all go into 16.
You then have to also multiply the numerators by the same number that you are multiplying the denominators by. 2 x X = 16 -> X = 8, so you multiply 1 x 8 and get 8, so the first fraction is 8/16. 16 x X = 16 -> x = 1, 3 x 1 = 3, so the next one remains 3/16. 8 x X = 16 -> X = 2, 2 x 7 = 14, so the last one is 14/16.
