Question

A group of students were given triangular cardboard pieces LMN to write slogan on global warming such that angle m=90 and mn=7 and LN=24 find cosL×sinL

Answer 1

0.28

Step-by-step explanation:

See the diagram attached.

Applying the Pythagoras Theorem the length of the line segment LM will be given by

$\sqrt{(LN)^{2} - (MN)^{2}} = \sqrt{24^{2} - 7^{2}} = 22.95$

So, $\cos L \times \sin L = \frac{ML}{NL} \times \frac{MN}{NL} = \frac{22.95}{24} \times \frac{7}{24} = 0.28$ (Approximate) (Answer)
