When they are the exact same, like carbon copies
Answer:
(n-2)180 (this is the equation to find the sum of interior angles)
(4-2) 180 (plug in the amount of angles in the polygon and then solve)
2* 180
360
360 - 115 -100- 73= 72 (360 is the sum of all angles for this polygon. so subtract the known angles to find the unknown one)
measure of angle B is 72 degrees
Step-by-step explanation:
Answer:
12/25
Step-by-step explanation:
48/100 simplifies to 24/50. 24/50 simplififes to 12/25.
Isolate the variables. You want to get the five on the same side as the ten, so, you add five to both sides.
-4b+2b=15
-2b=15
b= -7.5
I believe. You may want to double check my work though.
