We know that the sum of the interior angles of a triangle must equal to 180°.
So to find the missing angle on the inside of triangle FGH, we must subtract 53° and 45° from 180°:
So we know that the missing interior angle is 82°. We also know that a straight line has an angle of 180°.
x° + the interior angle that we just found must then equal to 180°, since ray HG is a straight line.
So we need to subtract 82° from 180° to find x°:
So now we know that
x° is equal to 98°.

<u>Answer:</u>
18 liters of jam after 9 days
<u>Step-by-step explanation:</u>
12 liters = 6 days
12 liters ÷ 6 days = <em>2 liters per day</em>
2 liters per day x 9 days = 18 liters of jam in 9 days
<em><u>Dave jarred 18 liters of jam in 9 days</u></em>
