Julian jogs 222 kilometers east, 444 kilometers north, and then 777 kilometers west.

Step-by-step explanation:

2 east -7 w= 5 west and 4 north

Now apply the pythagorean theorem.

a^2+b^2=c^2

5^2+4^2=c^2

 25+14=c 2

38 = c 2

sqrt (39) =c

c=6.244 Km

x = 10.1

step-by-step explanation:

all of the angles of a tirangle add up to 180º

180 - 65 = 115 (since we already know the value of one angle)

(2x + 7) + (8x + 7) = 115

(combins like terms) 10x + 14 = 115

(isolate the variable subtract 14 from both sides): 10x = 101

(find the variable divide both sides by 10): x = 101/10

x = 10.1
