Answer 1

Given :- Use Trigonometric Ratios to find the missing sides ?

Answer :-

we know that,

→ sin θ = Perpendicular / Hypotenuse

putting values we get,

→ sin 38° = x / 30

→ x = 30 * sin 38°

→ x = 30 * 0.616

→ x = 18.48 .

now, in second right angled ∆,

→ tan θ = Perpendicular / Base

putting values we get,

→ tan 25° = y / 14

→ y = tan 25° * 14

→ y = 0.466 * 14

→ y ≈ 6.5 .
