emilysmith1105:

ok so the interior angles of a triangle should always equal 180 degrees

emilysmith1105:

so you can add together the 2 angles you already know and subtract that from 180

emilysmith1105:

what would that be?

itzzalyssa:

uhhh one sec plz

itzzalyssa:

29?

emilysmith1105:

yes so now, you have 29 = (2x-3)

emilysmith1105:

so you can add 3 to both sides and get 32=2x

emilysmith1105:

solve from there

itzzalyssa:

13?

emilysmith1105:

32 divided by 2

itzzalyssa:

oh 16

emilysmith1105:

yep thats right so x=16

itzzalyssa:

ok thx
