Question

On walking ...... metres on a hill making an angle of measure 30 with the ground, one can reach the height of 'd' metres from the ground.select a proper option (a), (b), (c) or (d) from given options so that the statement becomes correct.
(a) √3/2*a
(b) 2a/√3
(c) 2a
(d) a/2

Answer 1

hypotenuse = a meter

height = d

$sin30 =\frac{d}{a}$

We know, value of sin30 is 1/2

hence, $d=\frac{a}{2}$

option d is correct.

Answer 2

Answer:

Step-by-step explanation:

D, a/2
