Kinda desperate here...

OpenStudy (anonymous):

Honestly, I don't remember. I am SOOO sorry. Geometry wasn't my strong suit.

ganeshie8 (ganeshie8):

hint : interior angles add up to 180 degrees in a triangle

ganeshie8 (ganeshie8):

\[x + 59 + 43 = 180\] solve \(x\)

OpenStudy (anonymous):

Oh, so the equation would be...180-(59+43)=X?

OpenStudy (anonymous):

78, right?

ganeshie8 (ganeshie8):

Yep!
