Which of the following could not be the measures of the angles of a triangle? A. 30^o - 120^o -30^o B. 40^o - 40^o - 100^o C. 60^o - 60^o - 60^o D. 70^o - 50^o - 70^o

D. 70^o - 50^o - 70^o

Step-by-step explanation:

The 3 angles of a triangle add to 180 degrees

A. 30^o - 120^o -30^o  = 30+120+30 = 180

B. 40^o - 40^o - 100^o  = 40+40+100 = 180

C. 60^o - 60^o - 60^o   = 60+60+60 = 180

D. 70^o - 50^o - 70^o   = 70+50+70 = 190  not a triangle

my guess would be b and d, but i didn’t actually get out the pen and paper. lol
