What is the Cos (A) in triangle ABC?

/
10 10
26 26
24 24

while using the law of sines I got

sin90/26=sinA/24

24sin90/26=sinA

sin^-1(24sin90/26)=(sinA)sin^-1

=67.380135052

But in this case it ask for the side which is 24 because it is across the angle A

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,

10 down (bang1)

5 up

5down (2)

2.5 up

2.5 down (3)

1.25 up

1.25 down (4)

now add them up : )

hoped i lol
