Answer:
1. x=28 degrees 2. x=70 degrees
Step-by-step explanation:
QUESTION ONE:
I know that 3x=84, so all I need to do is divide both by 3. I get x=28.
QUESTION TWO:
I can use vertical and complementary angles for this problem. I know that the smaller complementary angle is equal to 160-180, that's 20. Therefore, I get 90=20+x. If I simplify I get 70=x, because 70+20=90.
