3n + 17 + 4n + 16 = 180
solve n first
ganeshie8 (ganeshie8):
i saw few of ur videos in ur utube channel.. they're nice :)
ganeshie8 (ganeshie8):
can u solve n above ?
OpenStudy (anonymous):
just give me a sec
ganeshie8 (ganeshie8):
okie

in case you're stuck :-
3n + 17 + 4n + 16 = 180
combine like terms
3n + 4n + 17+16 = 180
7n + 33 = 180
7n = 147
n = 21
ganeshie8 (ganeshie8):
\(m\angle EFG = 3n+17 = 3(21) + 17 = 63 + 17 = 80\)
\(m\angle GFH= 180 - 80 = 100 \)
ganeshie8 (ganeshie8):
see if that makes some sense
OpenStudy (anonymous):
sorry for taking long, i'm a bit slow
ganeshie8 (ganeshie8):

little square box means, 90 degrees in geometry

ganeshie8 (ganeshie8):
Since FCD is a straight line,
90 + 64 + x = 180
solve x
OpenStudy (anonymous):
so 26?
ganeshie8 (ganeshie8):

ganeshie8 (ganeshie8):
good job :)
OpenStudy (anonymous):
ok i think this one is 150
ganeshie8 (ganeshie8):
this time, question is not about finding the value of angle as such
ganeshie8 (ganeshie8):
question is just asking us to name the angle in two other ways, thats all

do u see angle \(w\) in the pic ?
OpenStudy (anonymous):
yes
OpenStudy (anonymous):
is it an obtuse angle?
