Answer:
value of tan θ = 1
Step-by-step explanation:
To find θ do the asin of 1/√2
θ = asin (1/√2)
θ = asin (0.707106781)
θ = 45
and then to find tan θ, do tan 45
tan 45 = 1

Step-by-step explanation:
If the fan does 300 rev per min;
300 rev : 60 sec
x rev : 15 sec
x = 300 * 15 / 60
x = 75 rev
One revolution of the point on the blade is equal to the circumference of the circle with a radius of 10 cm. Therefore;
2πr
2* 3.14 * 10
= 62.83 cm
75 revolution will be;
75 * 62.83 cm
= 4712.39 cm
