6/8, 3/4 hopes this helps
B. Right (they are 90° angles)
D. Adjacent (they share sides)
G. Supplementary (the total of the 2 angles is 180°)
The sum of two supplementary angles is 180 degrees.
A+B=180.
80+B=180
B= 180-80
B=100
The answer is A
there is not enough hours to build everything and A has the right equation
