Answer:
40.4
Step-by-step explanation:
Triangle TUV is similar to triangle XYZ.
Notice the order in which TUV and XYZ are written.
Angles are corresponding to angles in the same position in the names.
<T corresponds to <X.
<U corresponds to <Y.
<V corresponds to <Z.
In similar triangles, corresponding angles are congruent.
<T is congruent to <X.
<U is congruent to <Y.
<V is congruent to <Z.
m<T = m<X = 63.1°
m<U = m<Y
m<V = m<Z = 76.5°
m<X + m<Y + m<Z = 180°
63.1° + m<Y + 76.5° = 180°
m<Y + 139.6° = 180°
m<Y = 40.4°
In mathematical form, it would be:
n-8 < 11
add 8 from both sides,
n-8+8 < 11+8
n < 19
So, n value must be less than 19

Answer: The distance of Observer A from the radio antenna is what fraction of the distance of Observer B from the radio antenna?
It is 1/4.
Step-by-step explanation:
We know that the intensity of electromagnetic waves decreases with the radius squared, this means that we can write a simple relation as:
Intensity(r) = A/r^2
Observer A measures 16 the intensity of observer B.
if Ia is the intensity that observer A measures and Ib is the intensity that observer B measures, we have that:
Ia = 16Ib
A/(ra)^2 = 16*A/(rb)^2
1/(ra)^2 = 16/(rb)^2
rb^2 = 16*ra^2
and we know that 16 = 4*4 = 4^2
rb^2 = (4*ra)^2
then rb = 4*ra
this means that the distance between observer B and the antenna is equal to 4 times the distance between observer A and the antenna.
The fraction is ra = rb/4
The distance of
