<EFD is also shown as e on the diagram. It is 90 degrees. <EFG is made up of the same two lines and is equal to 90 degrees (shown by the little box) so <EFD must be equivalent.
Answer:infinite solution
8(k - 6) + 58 = 2(4k + 5)
⇔ 8k - 48 + 58 = 8k + 10
⇔ 10 = 10
=> infinite solution
Step-by-step explanation:
None of the above answers are correct, the correct answer would be 15
Answer:
z = 33/5 or 6.6
x = 5/2 or 2.5
Step-by-step explanation:
20 = 5z - 13
Add 13 to both sides.
5z = 33
Divide both sides by 5.
z = 33/5 or 6.6
-9 + 2x = -4
Add 9 to both sides.
2x = 5
Divide both sides by 2.
x = 5/2 or 2.5
