Triangle ABC is isosceles (even tho' it doesn't look so).

m<BDE = m<BED because of that.

Thus, 66 degrees + 2 m<BDE = 180 degrees, and

2 m<BDE = 114 degrees. Thus, m<BDE = 57 degrees.

Yanka [14]

Answer:

Step-by-step explanation:

Create a proportion where x is the number of phone calls for 50 minutes on the phone:

$\frac{34}{17}$ = $\frac{50}{x}$

Cross multiply and solve for x:

34x = 850

x = 25

So, Nick would have to make 25 phone calls
