Answer:
x=6.86°
firstly set them equal
to each other
(7x+24)=72°
subract 24 from both sides:
7x=48°
divide both sides by 7 :
x=6.857.....
this can be rounded to :
x=6.86°
Midpoint is (X1+X2)/2 and (Y1+Y2)/2. Therefore it would be (10+8)/2 Which is 9.
And (2-3)/2 which is -1/2. THE MIDPOINT WOULD BE (9,-1/2)
5:30 - 2:40 = (5 -2):(30 -40) = 3:(-10) = 2:50
The roast must go into the oven at 2:50.
