2.
3x = 5x-10
solve for x
-2x = -10
x = 5 so gh = 5(5) -10
gh = 25 - 10
gh = 15
OpenStudy (anonymous):
oh okay, thanks on that one, i wasnt sure how to get x alone it always always confuses me
OpenStudy (anonymous):
what about number 3?
OpenStudy (anonymous):
and 4 should be 30 right?

OpenStudy (anonymous):
okay thank you. @jim_thompson5910 can you help me with 3 and 5?
jimthompson5910 (jim_thompson5910):
angles ABD and DBC are congruent (they are visually marked)
so 10y = 8y + 4
solve for y
OpenStudy (anonymous):
y=2?
jimthompson5910 (jim_thompson5910):
good

y =2
DBC = 8y+4
DBC = ???
OpenStudy (anonymous):
ohh ok, 20, but would i retricethe 15 to that also?
OpenStudy (anonymous):
add*
jimthompson5910 (jim_thompson5910):
where are you getting 15?
DBC is 20 degrees, so is angle CBE
so add them to get 40 degrees
OpenStudy (anonymous):
alright i got it. thank you
