Cosθ = 15/17
Step-by-step explanation:
Sinθ = 8/17
We know that,
Sin^2 θ + cos^2 θ =1
64/289 + cos^2 θ =1
1 - 64/289 = cos^2 θ
225/289 = cos^2 θ
Cos θ = √225/289
Cos θ = 15/17
Yes,according to the law of Detachment
Step-by-step explanation:
According to the law of detachment, in mathematical logic two statements are true;
a) If p then q
b)p
The we can derive a third statement q
Given: If the power has been cut, then the refrigerator does not work
Let p be the statement 'the power has been cut' and q be the statement 'the refrigerator does not work' the the two statements can be written as
1) If p the q
2) p
