Prove that:
(sin4a+sin2a) * (cos3a-cos5a) / (cos4a+cos2a) * (sin5a-sin3a) =tan3a*tan4a

f

step-by-step explanation:

f

v = 1/3 a^2h

step-by-step explanation:

if the height is 57.7cm and the height of the slant edge is 18.2cm, then the volume is 1/3 a^2h.

the highest percentage for deaths in construction from highest to lowest is as follows: falls, struck by objects, electrocution, and caught-in/between. these four are collectively known as fatal four.

in the case of falls, the type that is responsible for the overall highest death in the category is falls from roofs.
