Answer:
<DEF = 107
Step-by-step explanation:
The way to best solve this problem is by starting with angle F. Remember that all angles in a straight line must add up to 180. So by subtracting 135 from 180 we get 45 for angle F.
180 - 135 = 45
After that, we can figure out the measure of <DEF. All the angles of a triangle must add up to 180. So:
180 - 28 - 45 = 107
Making the answer 107 for the measure of <DEF
X = -1 and -1.5 so the 4th answer
Step-by-step explanation:
ANSWER He is 14 and she is 7 because 21 - 7 is 14
Answer:
4x +7y
Step-by-step explanation:
(8x +10y) +(-4x -3y) = x(8 -4) +y(10 -3) = 4x +7y
