Answer:
3. 160
4. 105
5. 95
6. 30
7. 86
8. 130
All triangles equal 180 so when you add the other 2 degrees in the triangle then subtract that by 180 then you get the third angle. The a straight line also equals 180 degrees so when you get the third angle subtract it by 180 then you get the answer to the "?"
That's how I was taught so, hope I got it all right! : )
It's Feedback A. B is wrong because natural numbers would be reversed with whole numbers, and c is wrong because irrational numbers would be outside.
Answer:
a) (![\sqrt[n]{x}](https://tex.z-dn.net/?f=%5Csqrt%5Bn%5D%7Bx%7D)
) the n will be 5 the x will be (-32/243)^2.
b) written the same as a. except the c will replace the n and x will be (2y)^b.
c) the answer will be 0.4^3.
d) the answer would be (st)^v/u.
Hope this helps!
