Answer:

$55^{\circ}$

Step-by-step explanation:

By the Vertical Angle theorem, $\angle 3 = 55^{\circ}$ .

By the parallel line theorem, $\angle 7 = \angle 3 = 55^{\circ}.$

So, $\boxed{\angle 7 = 55^{\circ}}$ and we're done!.

You bike 11.2 miles in 1.4 hours at a steady rate. What equation represents the proportional relationship between the x hour you

Elis [28]

Answer:

$\frac{x}{y}=8$

Step-by-step explanation:

Let the time for which i bike is = x hours

Let the distance traveled in x hours = y miles

Ratio of distance and time will be = x : y

I travel 11.2 miles in 1.4 hours then the ratio of time and the distance traveled will be 1.4 : 11.2 Or 14 : 112

then the ratio of distance and time will be same in both the cases

So equation will be

$\frac{x}{y}=\frac{14}{112}$

$\frac{x}{y}=8$

Therefore, equation representing the proportional relationship will be

$\frac{x}{y}=8$

Tanθ = opposite/adjacent
Tanθ = 64/48
arctan(64/48) = 53
90-53 = 37
48*Tan(37) = 36
64+36 = 100
