Supplementary and adjacent.
Two angles are called supplementary when their measures add up to 180 degrees.
Adjacent angles are two angles that have a common vertex and a common side but do not overlap.
perimeter means add the side
(x+4) +( x+8)+(2x-3) =P
x+x+2x+4+8-3=P
4x-9 =P
Answer:
40 Minutes.
Step-by-step explanation:
The current time = 4:12 p.M.
Emma's mom will be home from work in 70 minutes.
70 minutes = 1 hour 10 Minutes= 1: 10 Hours

Therefore, Emma's Mom will get home by 5: 22 p.m.
Emma has gymnastics lessons at 6 : 00 p.M.
To determine how much time Emma will have between the time that her mom gets home from work and the beginning of gymnastics lessons, we simply subtract 5:22 from 6.

Emma will have 40 Minutes.
-12 n - 24 = -12 (n+2)
-12 (n+2) is the answer
Answer:
the answer would be 180 degrees
