A hospital H receives a report about a serious road accident at C. An ambulance reaches the scene by traveling 5 km north, 15 km east, then 3km north. A helicopter travels directly from H to C. Their paths intersect at X. Find the distance from the hospital to X

  10 5/8 km

Step-by-step explanation:

Name the point 8 km north of the hospital point N. Then triangle NHC is similar to triangle AHX, where A is the point 5 km north of the hospital.

This means that ...

  HX/HC = HA/HN = 5/8

  HX = (5/8)HC

__

The distance HC can be found using the Pythagorean theorem. It tells you ...

  HC^2 = HN^2 +NC^2 = 8^2 +15^2 = 289

  HC = √289 = 17

so ...

  HX = (5/8)(17) = 10 5/8

The distance from the hospital to X is 10 5/8 km.

step-by-step explanation:

i could only see the first page. the other pages were blurry. ; -;

x hot dogs for 2$, y drinks for 3$. 29 items and total 70

2x+3y=70

x+y=29

if x=17and y=12

2(17)+3(12)=70

34+36=70
