Answer:
x = -3/8
Step-by-step explanation:
4(3-2x)=15
Distribute
12 -8x = 15
Subtract 12 from each side
12-8x-12 = 15-12
-8x =3
Divide each side by -8
-8x/-8 = 3/-8
x = -3/8
Starting from the fundamental trigonometric equation, we have
Since 
, we know that the angle lies in the third quadrant, where both sine and cosine are negative. So, in this specific case, we have
Plugging the numbers, we have
Now, just recall that
to deduce
Answer:
Step-by-step explanation:
At the point where two line cut across, the vertically opposite angles formed are equal. This means that
2x degrees = 78 degrees
Dividing the left hand side and the right hand side of the equation by 2, it becomes
2x/2 = 78/2
x = 39
Checking,
The sum of the angles on a straight line is 180 degrees.
180 - 78 = 102 degrees
2x + 102 = 180
2x = 180 - 102 = 78
x = 78/2 = 39
