Answer:
You can use a period or a circle (not colored in)
Answer: you simplfy the two equations already there then plug them in to find factors
Step-by-step explanation:
1)73 degrees
all the angles of a triangle add up to 180 degrees.
23+84= 107
180-107=73
2) 28 degrees
110+42= 152
180-152= 28
Answer:
3x+15= 4x-10
3x-4x= -10-15
-x= -25(minus will be cut on both sides)
so x= 25
