Step-by-step explanation:
w(2w - 30) = 5400
2w²- 30w = 5400
2w² - 30w - 5400 = 0
(w - 60 ) ( w + 45 ) = 0
w= 60 w= - 45
only take the positive value
therefore w = 60

Answer:
um, your showing us an answer
Step-by-step explanation:
basically, they're saying that
w = 9. So 9-9=0
we know that
If lines m and n are parallel
then
m<1 and m<5 are corresponding angles
so
m<5=m<1
therefore
m<5=135 degrees
