4. As line SU and TV are intersecting each other at O.
A.T.Q, ∠UOV = (7x - 4)°
∠SOT = 87°
Then, ∠UOV = ∠SOT {Vertically Opposite Angles}
![\rightarrow\sf{7x - 4=87}](https://tex.z-dn.net/?f=%5Crightarrow%5Csf%7B7x%20-%204%3D87%7D)

3. ∠1 and ∠2 - add to 180 (linear pair)
∠1 and ∠3 - equal (Vertically Opposite Angles)
∠3 and ∠4 - add to 180 (linear pair)
∠2 and ∠4 - equal (Vertically Opposite Angles)
_______________________________________
2. 160° + (6x - 16)° = 180° (linear pair)
![\rightarrow\sf{6x - 16 = 180-160}](https://tex.z-dn.net/?f=%5Crightarrow%5Csf%7B6x%20-%2016%20%3D%20180-160%7D)

![\rightarrow\sf{6x = 20+16}](https://tex.z-dn.net/?f=%5Crightarrow%5Csf%7B6x%20%3D%2020%2B16%7D)
![\rightarrow\sf{6x =36}](https://tex.z-dn.net/?f=%5Crightarrow%5Csf%7B6x%20%3D36%7D)
![\rightarrow\sf{x =\frac{36}{6}}](https://tex.z-dn.net/?f=%5Crightarrow%5Csf%7Bx%20%3D%5Cfrac%7B36%7D%7B6%7D%7D)
![\rightarrow\boxed{\bf{x =6}}](https://tex.z-dn.net/?f=%5Crightarrow%5Cboxed%7B%5Cbf%7Bx%20%3D6%7D%7D)
Answer:
I think it's 12.
Step-by-step explanation:
3(-2)^2 in a calculator give you 12
= -8/3 + 4/6
= -16/6 + 4/6
= -12/6
= -2 answer
3,657,892
3 is in the millionth place.
6 is in the hundred-thousandth place.
5 in in the ten-thousandth place.
7 is in the thousandth place.
8 is in the hundredth place.
9 is in the tenth place.
2 is in the unit place.
I don't know if I worded this completely properly, but the answer should still be right!
