When 2 negative numbers are multiplied they turn positive but if you divide you get a negative as well is you subtract but if you add you must add a greater number to take i out of the negative side to put it in the positives
Step-by-step explanation:
-6 + 7 = 2x
1 =2x
If you have to find the value of x then
1/2 = x
The value of the angle ∠AVB is 53°, side VB = 132.83 m, side OV = 119 m
<h3>How to find the side length from bearings?</h3>
8) From the given triangle we see that;
∠VAO = 37°
∠VBO = 64°
∠VOA = 90°
a) Now, we know that sum of angles in a triangle is 180°. Thus, for triangle AVO, we can say that;
∠VAO + ∠VOA + ∠AVB = 180°
37 + 90 + ∠AVB = 180°
∠AVB = 180° - 127°
∠AVB = 53°
b) Using triangle rules we can say that;
tan 64 = VO/BO
Similarly, we can say that;
tan 37 = VO/(100 + BO)
Dividing both equations gives;
tan 64/tan 37 = (100 + BO)/BO
2.72BO = 100 + BO
1.72BO = 100
BO = 58.14 m
Using trigonometric ratio;
58.14/VB = cos 64
VB = 132.83 m
c) OV/132.83 = sin 64
OV = 132.83 * sin 64
OV = 119 m

Answer:
Step-by-step explanation:
|√2-y|=|y-√2|
√2-y=±(y-√2)
when √2-y=y-√2
y+y=√2+√2
2y=2√2
y=√2
when √2-y=-(y-√2)
√2-y=-y+√2
or 0=0
it gives no value of y.
so only possible value is y=√2
