Josh is hiking Glacier National Park. He has now hiked a total of 17 km and is 2 km short of being half of the way done with thi
poizon [28]
Hello!

What we know so far is that Josh has hiked 17km. He is 2km short of being half way done with the hike.

To solve this, we must add 17 and 2 (to find the kilometers that he has hiked and the kilometers that he needs to hike to reach half way.)
17+2= 19

Now we know that 19km is exactly halfway in Josh's hike.
To find the total amount of km in Josh's hike, we must multiply 19 by two. (Half way times two = total amount)

19x2= 38

The total amount of kilometers in Josh's hike is 38km.

I hope this helps you!!

Marysya12 [62]

Answer:

Angle DBC = 51

Step-by-step explanation:

Angle ABC = angle ABD + angle DBC

We are given that angle ABC = 122 and angle ABD = 71

So 122 = 71 + angle DBC

* Solve for angle DBC *

Subtract 71 from both sides

122 - 71 = 71 - 71 + angle DBC

51 = angle DBC
