Answer:
x = 6
Step-by-step explanation:
Assuming the figure is a parallelogram then opposite sides are congruent, thus
3x - 6 = 12 ( add 6 to both sides )
3x = 18 ( divide both sides by 3 )
x = 6
Answer:
r= 1/3
Step-by-step explanation:
This is because if you plug in the number 15 and 5 you would get 5=r15
Then you would divide 15 by both sides to get 0.3 repeat. You can leave it like that or turn it into a fraction which is 1/3
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
