Question

Answer part A and part B

Answer 1

`\sf\large \green{\underbrace{\red{Answer⋆}}}:`

[A] Right option is C

[B] 11.55

Explanation:

`\sf \tan A{ \degree} = (Perpendicular)/(Base)`

• here perpendicular is 20
• and base is x

`\sf \tan 60{ \degree} = (20)/(x) \\ \sf x = \frac{20}{ \tan60{ \degree}}`

now we need to find value of x

tan 60° = √3

`\sf x = (20)/( √(3) )`

first we need to rationalize by multiplying √3 in numerator and denominator

`\sf x = (20 √(3) )/(3) \\ \sf x = (34.64)/(3) \\ \sf x = 11.55`
