Answer 2

⭐Solution⭐

✒given here

2 sin o -1 = 0......(1)

✏Find here .

sec o + tan o=❓

By (1)

♣ sino = 1/2

So,

♣ tan o = 1/√3

♣ sec o = 1+tan ²o

= 1+(1/√3)²

= (3+1)/3

= 4/3

so,

tan o + sec o = 1/√3 + 4/3

= (3+4√3)/3√3

= (3+4×1.732)/(3×1.732)

= (3+6.928)/(5.196)

= 9.928/5.196

= 1.91
