For positive acute angles A and B, it is known that tan A = 2. and cos B = 15.
Find the value of sin(A + B) in simplest form.

answer:  

step-by-step explanation:

here x represents the height of the pole,

and, the height of the shadow of the pole is 12 feet.

also, the angle of elevation from the top of the pole is 40°,

therefore,

by the low of sine,

which is the required equation for finding the value of x,

225x²+4=0

225x²=0-4

225x²=-4

x²=-4/225

x=±√-4/225

41*67/2=1373.5
