Question

please help in solving the following question ​

Answer 1

Step-by-step explanation:

if 5cos0 = 7sin0

the tan0 = 5/7

now,

(7sin0 + 5cos0) / (5sin0 + 7cos0)

dividing both numerator and denominator by cos0

(7tan0 + 5) / (5tan0 + 7)

(5+5) / (25 + 49)/7

70 / 74

30/37

Answer 2

Answer:

according to question :-

5cos Φ = 7 sin Φ

cos Φ/sinΦ = 7/5

cos Φ = 7

sin Φ = 5

now putting values in question :-

7sinΦ+ 5cos Φ/ 5sin Φ + 7cos Φ

7*5 + 5*7 / 5*5 + 7*7

35+35 / 25+49

70/44

35/22

hope you understand plz thank my answer
