16. ∠2 = 53° because it is supplementary.
- You are given the measurement of ∠1, which is 128°. From the picture you can see that ∠1 and ∠2 combined equal 180° (they are supplementary angles).
- So to find ∠2, simply subtract 128° from 180°. The answer is 53°.
------------------------------------------------
17. 12° because it is vertical.
- Vertical angles, like 48° and 4x in the image, are always equal.
- So if 4x = 48°, then you can divide both sides to get x = 12°.
Answer:
should be (4a-5)x(4a+5)
Step-by-step explanation:

He isn't right. He needs 1/6 cup of olive oil since 2/3 times 1/4 = 1/6
The answer is 8i.
i = √(-1)
√(-64) = √((-1) * 64)
= √(-1) * √64
= i * √8²
= i * 8
= 8i
