answer:

Part B for now

Step-by-step explanation:

So you need to find the value of B first. So what you want to do is find the value of the other angles in terms of B. A is two times the value of B so A will be "2B" and C is 5 degrees more than A so C will be "2B + 5" Then add them all together you get (5B+5= 180). You subtract the 5 from both sides and then divide by 5 and you get the angle of B. Then simply plug it back in and find the other angles based on "2B" and "2B + 5"

just do 5.2 + 2 ( 7.2) and 1/3 x 3 (.9) and youv'e got your equation. 0.9( 9/10) + 7.2 ^2 = 16.4 hope i could !

step-by-step explanation:

54 km / hours

step-by-step explanation:

we need to convert seconds to hours

60 seconds = 1 minutes

60 minutes = 1hour

15 m         60 second   60 minutes

  * *         = 54000 meters/ hour

second     1 minute             1 hour

now we need to convert meters to km

1000 m = 1 km

54000 m       1 km

*   = 54 km / hours

hour               1000m
