Can somebody give me a detailed equation for this angle, I already have some but i need more thank you.

47 + 2x - 3 = 90

OR

2x - 3 + 47 = 90 (same equation but order of angles reversed)

x = 23

Step-by-step explanation:

47 + 2x - 3 = 90

44 + 2x = 90

(44 - 44) + 2x = 90 - 44

2x = 46

2x/2 = 46/2

x = 23

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,
