Question:

If tanA =\(\frac{2.4}{0.7}\), then

find the value of (50 cosA + 24 cotA)

Options:

21

26

37

34

Correct Answer:

21

Explanation:

tanA =\(\frac{2.4}{0.7}\)=\(\frac{24}{7}\)=\(\frac{P}{B}\)   [Triplet 24, 7, 25]

H = 25

⇒ 50 cosA + 24 cotA

= 50 × \(\frac{7}{25}\) + 24 × \(\frac{7}{24}\)

= 14 + 7 = 21
