Answer:

The measure of angle C is $30\°$

The draw in the attached figure

Step-by-step explanation:

see the attached figure to better understand the problem

we know that

In the right triangle ABC

The sine of angle C is equal to divide the opposite side to angle C by the hypotenuse

$sin(C)=\frac{AB}{AC}$

substitute the values

$sin(C)=\frac{4.5}{9}$

$C=arcsin(\frac{4.5}{9})=30\°$

Ana drew a map of the Panama Canal. In the scale Ana used for the map, 4 centimeters represents 20 kilometers. The actual length

yawa3891 [41]

Answer:

Length of the canal on the map is 16.4 centimeters.

Step-by-step explanation:

If actual length of Panama Canal = 20 kilometers

and length of the canal on map = 4 centimeters

Then scale factor = $\frac{\text{Length of canal on map}}{\text{Actual length of canal}}$

= $\frac{4}{20}$

= $\frac{1}{5}$

If the actual length of Panama Canal = 82 kilometers

Then the length of canal on the map = Actual length × Scale factor

= $82\times \frac{1}{5}$

= 16.4 centimeters

Therefore, length of the canal on the map is 16.4 centimeters.

love history [14]

Answer:

She need to walk 31/75 miles to school.

Step-by-step explanation:

It is given that,

Sofia has walk $1\dfrac{2}{25}$ miles to school. She has already walk $\dfrac{2}{3}$ of a mile.

We need to find how much farther does she need to walk.

Total distance = $1\dfrac{2}{25}$ $=\dfrac{27}{25}$

Let she has to walk x distance to school.

$x=\dfrac{27}{25}-\dfrac{2}{3}\\\\=\dfrac{31}{75}$

Hence, she need to walk 31/75 miles to school.
