Before they leave the zoo, Jacob's dad takes a look at the map to find the best route to their next destination. On the map, the highways 125, 143, and 17 are all parallel to each other. Certain lengths are shown in the map below. Figure out how long, in hours and minutes, it will take Jacob's dad to get from highway 125 to highway 17 if he is traveling along highway 84 at 65 mph (to the nearest minute).

i don't see any steps below, sweetheart

130 degrees. i have no other way to explain

  b:   ∠x = 28.6°, ∠y = 31.2°, ∠z = 120.2°

step-by-step explanation:

this is one of those questions where "test taking skill" is all you need. the only answer that has angles that sum to 180° is the one shown above. the remaining choices do not describe the angles of a triangle.

if you want to do more work than simply adding the offered numbers, you can also check them against the law of sines. it should be true that

  x/sin(x) = y/sin(y) = z/sin(z)

and all of these ratios must be greater than 15, the longest side length.

if you want to solve the triangle from scratch, i'd suggest solving for the largest angle using the law of cosines.

  z² = x² +y² -2xy·cos(z)

  z = arccos((x² +y² -z²)/(2xy)) = arccos(-75.11/149.4) = 120.182°

now you can find y from the law of sines

  y = arcsin(y/z·sin(z)) = 31.242°
