The opposite of 12 is -12 . To add negative numbers to positive numbers count backwards, as if you were subtracting. We have the problem: 1+ (-12). This can be read as “one plus negative twelve.” This can also be read as 12-1 which is 11 so the answer is 11.

Find the value for x

d1i1m1o1n [39]

Answer:

Value of x --> 15°

Step-by-step explanation:

(2x + 60°) and 6x lie on a straight line. So, they form a linear pair. Their sum gives 180°.

---> (2x + 60°) + 6x = 180°

2x + 60° + 6x = 180°

8x + 60° = 180°

8x = 180°- 60°

8x = 120

x = $\frac{120}{8}$

<h3>x equals 15°</h3>
