1 answer:

6 0

(1-cos^2x/cosx)*cosecx
(sin^2x/cosx)*sinx (where 1-cos^2x=sin^2x) and 1/cscx=sinx

sinx/cosx=tanx(divide by sinx)
hence proved

A right triangular prism has a height of 26 cm and base edges of 10 cm, 24 cm, and 26 cm. What is the lateral area of the prism?

horrorfan [7]

The lateral area is 1560 cm².

The lateral area is the area of the lateral faces (the faces that are not bases). The dimensions of these are:
24 by 26
10 by 26
26 by 26

These are all rectangles. The area of each rectangle is given by length * width:
24*26 = 624
10*26 = 260
26*26 =676

624+260+676=1560
