w - 10 + w - 38 + w + 36 = 180

3w - 48 + 36 = 180

3w - 12 = 180

3w - 12 (+12) = 180 (+12)

3w/3 = 192/3

w = 64°


hope this helps

first add all of the numbers, which is -10+-38= -48+36=-12
then since triangles are 180 degrees, 180 - - 12= 192
192/3 = 64
so i think that 64 is w
so put 64 in place of all the w's
