Well...it says the sum of the angles measure 360...so lets set them equal to 360
40 + x - 10 + 1/3x + x - 20 = 360...combine like terms
2 1/3x + 10 = 360
7/3x = 360 - 10
7/3x = 350
x = 350/(7/3)
x = 350 * 3/7
x = 1050/7
x = 150 <=====
7/12 is less than 3/4.
Check: 3/4 is same as 9/12. Clearly see that 7/12 is less than 9/12
Answer:
the answer is e=mc^2 I think
Theres not enough information to properly answer this.
Given:

To find:
The function
.
Solution:
we have,

Put g(x)=y.

Interchange x and y.

Isolate y.



Substitute
.



Therefore, the correct option is (3).
