To start let's add 23 and 21
23+21=44
then since it's asking for 1/3 we'll divide 44 by 3 which is 14 1/3
so 1/3 the sum of 23 and 21 is 14 and 1/3
I hope I've helped!

Answer:
-2/4
Step-by-step explanation:
-4/5 × 10/16
= 2/-4
= -2/4
Supplementary angle = 180 degrees
angle 1 = x
angle 2 = 3x (three times the supplementary)
3x + x = 180
4x = 180
x = 45 degrees
angle 1 = 45 degrees
angle 2 = 135 degrees
