-3x+ 4=1 and -12x -27=324
Answer:
A
Step-by-step explanation:
73+107 = 180. When the smaller of the two angles is 73 all of the smaller angles are also going to be 73 and since the angles MTS and STN are bigger angles they both have to be 107
Answer:
3-2x=15
Step-by-step explanation:
add 3 to both sides makes -2x=18. divide -2 from both side gets the answer x=-9, so the answer is C, -9
The sum of a polygon's angles are 540.
When you add all the angles together here, you get 456.
Now subtract 456 from 540.
540 - 456 = 84
