Step-by-step explanation:
Given:
In triangle KLM, KL = 123 cm and measure of angle K is 35 degrees.
To find:
The length of the side KM to the nearest tenth of a centimeter.
Solution:
In a right angle triangle,

In the given right triangle KLM,



Multiply both sides by 123.



The measure of side KM is 100.8 cm.
Therefore, the correct option is (2).
11km = 5h
1km = 5h divide by 11km = 0.45h
16.5km = 0.45 x 16.5 = 7.42 h
