The last angle would be 70 degrees
As there is 180 degrees in a triangle so you add the angles you know and then subtract it from 180
37+73=110
180-110=70
Answer: 70°
Step-by-step explanation: The missing angle would be 70°. This is because if you add up 73° and 37° it equals to 110. Subtract 110 from 180 and you get 70°.
