Answer: B
It is 30 degrees. Add 90 and 60 to get 180. Then subtract that from 180, since all triangles interior angles add to 180. You’ll get 30.
Answer:
17 is C
18 is add
19 is C
Step-by-step explanation:
Question 18 is worded a little weird.
so. (x^2)(x^3) = x^5, so you should add the expotents when you are multiplying them.
99% = 99 / 100 = 0.99
79.9 is 99% of what
= 79.9 / 99
=79.9 / 0.99
