Answer:
x = 6
Step-by-step explanation:
We solve that above question using the trigonometric function of Tangent
Tan theta = Opposite/Adjacent
Theta = 45°
Opposite = 6
Adjacent = x
tan 45° = 6/x
tan 45 in rational form = 1
1 = 6/x
Cross Multiply
x = 6
It is given in this question that angle 1 and angle 2 are linear pair .
LInear pair are those angles , whose sum is 180 degree.
That is sum of measurements of angle 1 and angle 2 must be 180 degree. That is
Combining like terms
Subtracting 46 from both sides
Dividing both sides by 2
So the two angles are
This situation can be represented by
y = 33x + 223
y = 32x + 239
I still like substitution, so let’s plug in 33x + 223 into the second equation
33x + 223 = 32x + 239
Move the terms into appropriate sides
33x - 32x = 239 - 223
Combine like terms
x = 16
Then plug in x for any equation
y = 32(16) + 239
y = 751

Hi there!
The sample is biased because it is 600 customers that like the product, and, 600 compared to the world population is very small, so this is a bad sample.
Hope this helps!
