C. P+0.085p=$368.90. 1.085p=$368.90. $368.90/1.085=$340. The original cost was $340 :)
Answer:
1) 25 miles
2) 20 m
Step-by-step explanation:
Number 1 is going to be
because it's a right triangle
So
+
= 
625 = 
c = 25 mile
Number 2 uses the same process, but changing to using C instead of A
a^2 = c^2 - b^2
a^2 = 625 - 225
a = \sqrt(400)
a = 20m
Answer:
Below.
Step-by-step explanation:
If its a right triangle it will obey the Pythagoras theorem.
17^2 = 289
11^2 + 15^2 = 121 + 225 = 346
- so NOT a right triangle.
