Answer:

Step-by-step explanation:
Opposite angles of an inscribed quadrilateral are supplementary, so ...
m∠A + m∠C = 180°
Substituting the given expressions, we have ...
(3x +6)° + (x+2)° = 180°
4x +8 = 180 . . . . . . collect terms, divide by °
x +2 = 45 . . . . . . . . divide by 4
3x +6 = 135 . . . . . . multiply by 3
This is the value of angle A in degrees, so ...
m∠A = 135°

Step-by-step explanation:
Answer:
x=-2
Step-by-step explanation:
Step 1: Subtract 8x from both sides.
5x+6−8x=8x+12−8x
−3x+6=12
Step 2: Subtract 6 from both sides.
−3x+6−6=12−6
−3x=6
Step 3: Divide both sides by -3.
−3x
−3
=
6
−3
x=−2
In 30 hours he will go 25 miles and you can divide by 3 to get ten hours
25/3= 8.33333333 so on so on.
