Question:

If tanA =\(\frac{1.5}{0.8}\), then

find the value of (34 cosA + 15 cotA)

Options:

32

24

16

20

Correct Answer:

24

Explanation:

tanA =\(\frac{1.5}{0.8}\)=\(\frac{15}{8}\)=\(\frac{P}{B}\)   [Triplet 15 , 8 ,17]

H = 17

⇒ 34 cosA + 15 cotA

= 34 × \(\frac{8}{17}\) + 15 × \(\frac{8}{15}\)

= 16 + 8 = 24
