Answer:
w = 10
Step-by-step explanation:
3w = 30
Divide each side by 3
3w/3 = 30/3
w = 10
I think that the answer is c
You will have to find what x is to get your answer solve each to find the answer
It’s c. Where the two planes intersect
Answer:
DC = 2
Step-by-step explanation:
The wrong equation was used.
The right equation to use based on the midsegment theorem of a trapezoid is:
MN = ½(AB + DC)
MN = 8
AB = 14
Substitute
8 = ½(14 + DC)
Multiply both sides by 2
8*2 = ½(14 + DC)*2
2*8 = 14 + DC
16 = 14 + DC
16 - 14 = 14 + DC - 14
2 = DC
DC = 2
