Question

In right angled ∆LMN, Angle LMN = 90°
Angle L = 50° and Angle N = 40°,
write the following ratios.
(i) sin 50°
(ii) cos 50°
(iii) tan 40°
(iv) cos 40°
​

Answer 1

Answer:-

Formula used:-

1. Sin θ = Perpendicular/ Hypotenuse
2. Cos θ = Base/ Hypotenuse
3. Tan θ = Perpendicular/Base

(i) Sin 50° = MN / LN

(ii) Cos 50° = LM / LN

(iii) Tan 40° = MN / LM

(iv) Cos 40° = LM / LN

It is not able to find their length as none of the length is provided

Answer 2

Answer:

sin 50°= MN/LN

cos 50°=LM/LN

tan 40°=LM/MN

cos 40°=MN/LN
