11 - 6 = 5
5 ÷ 2 = 2.5
Final answer: 2.5 miles
Option A
<em><u>Solution:</u></em>
Given that we have to rewrite with only sin x and cos x
Given is cos 3x
We know that,
Therefore,
---- eqn 1
Substituting these values in eqn 1
-------- eqn 2
Applying this in above eqn 2, we get
Option A is correct
2x+6=60
2x=60-6
2x=54
x=54/2
x=27
27+27+6=60
True
