Answer:

Step-by-step explanation:
Since ED is parallel to CA, the two triangles in the figure share all 3 angles and therefore must be similar. By definition, the corresponding sides of similar polygons are in a constant proportion.
Therefore, we have:

Answer:
1 a. warmer
b. -8 is closer
c. -2 degrees
d.his elevation is 10 ft below sea level
2 a.0
b. -300
c. -450
3 Basically a fraction is division so divide the numerator by the denominator to get the calculation. For example 2.1 divided by 1.5 equals 1.4.
Sin^2 + cos^2 = 1
so,
(x/4)^2 + (y/4)^2 = 1
we got rid of t.
there are 6 1/6 per hour
multiply 1/3 by 6
1/3 * 6 = 6/3 = 2 miles per hour
