Use Tangent(Tan) function
Tan( 26) = opposite(tall( / Adjacent(shadow)
Tan(26) = opposite(tall) / 82 feet
Algebraically rearrange
opposite(tall) = 82feet*Tan(26)
NB Do NOT write as ' Tan(26)82ft ' , as it confuses the numbers under the Tan function.
Hence
Height = 82ft * 0.4877326886....
Height = 39.9940... ft ~ 40 feet.
When the angle of elevation equals 45 degrees. tan-1(1) = 45 degrees.
It is: 27.35 degrees rounded to two decimal places
Besides the shadow, you also need the angle of elevation. Then the height can be found .
Angle of elevation = 300/50 = 6 tan-1(6) = 80.53767779 degrees or 800 32' 15.64''
It is: tan(52)*9 = 11.519 meters rounded to three decimal places
36 degrees
If you also know its shadow then you can work out the angle of elevation
If we assume the the flagpole makes a 90 degree angle with the ground, then the angle of elevator for the sun is 34.778°
Use the tangent ratio: tan = 22.5/34 = 45/68 tan-1(45/68) = 33.49518467 degrees Angle of elevation = 33o29'42.66''
21metres
To find the angle of elevation of the sun, we can use the tangent function in trigonometry. The angle of elevation (θ) can be calculated using the formula: tan(θ) = opposite/adjacent. Here, the height of the flagpole (55 feet) is the opposite side, and the length of the shadow (16 feet) is the adjacent side. Thus, θ = arctan(55/16), which gives an angle of approximately 74.74 degrees.
The angle of elevation of the sun can be determined using the tangent function in trigonometry. Specifically, if the height of the flagpole is ( M ) and the length of the shadow is ( m ), the angle of elevation ( \theta ) can be calculated using the formula ( \tan(\theta) = \frac{M}{m} ). To find the angle, use ( \theta = \arctan\left(\frac{M}{m}\right) ). This angle represents how high the sun is in the sky relative to the horizontal ground.
When the angle of elevation equals 45 degrees. tan-1(1) = 45 degrees.
Use the Tangent function Tan(angle) = opposite(height) / adjacent(shadow) Substituting Tan )53) = height/ 12m Algebraically rearrange height = 12m X Tan (53) NB Make sure your calculator is in 'Degree' Mode. Then type in '12' 'X' , '(' , 'Tan', '53', ')' , '=', The answer should 'pop ip' pm the screen . height = 15.92453786...m Approx. ht. ~ 15.92 m ( 2 d.p.).
You can use trigonometry to find the angle of elevation. Let x be the distance from the tip of the shadow to the base of the pole and the height of the pole be y. Then, tan(60 degrees) = y/x. Given that the height of the pole is 12 feet, you can solve for x to find the angle of elevation.
It is: 27.35 degrees rounded to two decimal places
