The direct distance from a starting point to a finish line is 15 miles. Unfortunately, you can't take the direct route. If you travel 12 miles east, how many miles north must you travel to reach the finish line? 10 19 9

9 miles

Step-by-step explanation:

From Pythagoras :

Opposite^2 = Hypotenus^2 - Adjacent^2

The direct route = 15 miles = hypotenus

x² = 15^2 - 12^2

x² = 225 - 144

x² = 81

x =. Sqrt(81)

x = 9

Hence, you must travel 9 miles north

step-by-step explanation:

0

11.2

step-by-step explanation:

when doing tangent the tangent of the angle is equal to the opposite side from the angle over the adjacent side to the angle.

tan43 = x / 12

move 12 over by multiplying each side by 12

12tan43 = x

x = about 11.2
