Question

In a Triangle LMN ,<L=30,LM perpendicular to MN,<N=60 and If MN=8cm. Find the length of remaining sides. ( <N= read as angle N)​

Answer 1

Step-by-step explanation:

<L & < N are 30° & 60° respectively, so <M = 90°.

The triangle ∆LMN is a right-angled triangle.

ATP,

MN(base/b) = 8cm

LM is perpendicular (p)

and LN is hypotenuse (h)

Using trigonometry,

cos60° = b/h

tan60° = p/b

Hope this will help. Do it yourself now by putting the values of everything.
