Question

Find the angle of elevation of sun at different times as at 9.00 am, 2.00 pm and 5.00pm. For this project you need a stick about 100 cm long . At the given times you put the stick vertical and measure its length of shadow. Then using tanx = length of stick/ length of shadow . find the value of x using trigonometric table given in your maths book at the end.




​

Answer 1

Step-by-step explanation:

At 9: 00 am ,

The length of stick = 90 cm

length of shadow = 45 cm

Then,

Tanx = 90cm/45cm

Tanx = 2

So,

x = 2/tan
