5.0km
7.5km
7.6km
8.7km
Correct answer is D
\((PR)^2 = (PQ)^2 + (QR)^2\)
\(10^2 = 5^2 + (QR)^2\)
\((QR)^2 = 100 - 25\)
\(QR = \sqrt{75}\)
= \(8.660\)
\(\approxeq\) 8.7 km

the consumers and producers living in a habitat
living organisms interacting with physical factors of an environment

Given that sin \(P = \frac{5}{13}\), where p is acute, find the value of cos p - tan p
\(\frac{79}{156}\)
\(\frac{85}{156}\)
\(\frac{7}{13}\)
\(\frac{8}{1}\)
Correct answer is A
If \(sin P = \frac{5}{13}\) from right angled triangle from pythagoras theorem
\(BC^2 = 13^2 - 5^2\\
=169-25\\
BC = \sqrt{144} = 12\\
∴ cos P - tan P = \frac{12}{13} - \frac{5}{12}\\
=\frac{79}{156}\)
