Question

Evaluate: sin 70/ cos 20 + cosec36/ sec54 (for cbse class 10)​

Answer 1

Answer:

2 is answer

Step-by-step explanation:

convert sin 70 into cos and cosec36 into sec

Answer 2

Answer:

ans = 2

Step-by-step explanation:

Sin70 = Sin (90-20) = Cos 20

Cosec 36 = Cosec(90-54) = Sec54

now

sin 70/ cos 20 + cosec36/ sec54

Cos20/Cos20 + Sec 54/ Sec 54

1 + 1 = 2
