Answer:
86
Step-by-step explanation:
This is because the angles should add up to 180. So 32 + 64 is 96. Then you subtract 96 from 180 to get 86.

Answer: the first one is True and the second one is false
Step-by-step explanation:
3 + 5x = 23
so replace x with 4 you get 3 + 5 * 4 = 3 + 20 = 23
this is equal to 23 so it is true
2x - 6 = 9
do the same you get
2 * 8 - 6 = 9
16 - 6 = 10
the answer is 10 not nine therefore it is false
