Answer:

11 stories apart

Step-by-step explanation:

We let the "ground" be considered at height = 0

Anything above, is POSITIVE direction

Anything below, is NEGATIVE direction

8 stories are ABOVE, so that would be considered

+8

3 stores are BELOW, so that would be considered

-3

THe difference in height between them is:

8 - (-3) = 8 + 3 = 11

So, that is 11 stories apart (top and bottom)

Angles U and V are supplementary angles. The ratio of their measures is 7:13 Find the measure of each angle
GREYUIT [131]
If u and v are <span>supplementary angles, then

u+v=180^{\circ}~~~~~\mathbf{(i)}


The ratio of u and v is \dfrac{7}{13}:<span>

\dfrac{u}{v}=\dfrac{7}{13}\\\\\\ u=\dfrac{7v}{13}~~~~\mathbf{(ii)}


Substitute \mathbf{(ii)} into \mathbf{(i)}:

\dfrac{7v}{13}+v=180^{\circ}\\\\\\ \left(\dfrac{7}{13}+1 \right )\cdot v=180^{\circ}\\\\\\ \left(\dfrac{7}{13}+\dfrac{13}{13} \right )\cdot v=180^{\circ}\\\\\\ \dfrac{20}{13}\cdot v=180^{\circ}\\\\\\ v=180^{\circ}\cdot \dfrac{13}{20}\\\\\\ \boxed{\begin{array}{c} v=117^{\circ} \end{array}}


From \mathbf{(i)}, we find the measure of u:

u=180^{\circ}-v\\\\ u=180^{\circ}-117^{\circ}\\\\ \boxed{\begin{array}{c} u=63^{\circ} \end{array}}
