Question

the angle of elevation of a ladder leaning against a wall is 60 degree and the foot of the ladder is 9.5 away from the wall find the length of the ladder​

Answer 1

Step-by-step explanation:

cos 60° = height of ladder/distance

cos 60° = height of ladder/distance=> 1/2 = height of ladder/9.5

cos 60° = height of ladder/distance=> 1/2 = height of ladder/9.5=> height of ladder= 9.5×2=19m

cos 60° = height of ladder/distance=> 1/2 = height of ladder/9.5=> height of ladder= 9.5×2=19m4.5

cos 60° = height of ladder/distance=> 1/2 = height of ladder/9.5=> height of ladder= 9.5×2=19m4.5follow me

cos 60° = height of ladder/distance=> 1/2 = height of ladder/9.5=> height of ladder= 9.5×2=19m4.5follow me like me
