Answer:
-6
Step-by-step explanation:
8x/3 - 2x/4 = -13
find the L.C.M
<u>32x - 6x </u> = -13
12
<u>26x </u> = -13
12
cross multiply
26x = -156
divide both sides by 26
26x/26 = -156/26
x = -6
Option A is the answer
Since 29 + 39 = 68, the answer cannot be possible.
Essentially, any two sides of a triangle have to be greater than another side.
The end point for a 192 degree angle is located in the third quadrant, where both x and y are negative, so both sin192, cos192 are negative.
