Question

Which equation could be used to find the height of the flagpole?

a. x/5 = sin 50

b. x/5 = cos 50

c. 5/x = tan 50

d. x/5 = tan 50

Answer 1

Given a fragpole which makes a right angle with the point of observation with the angle of elevation as 50°.

Let x be the height of the flagpole, then


`\sin50^o= (x)/(5)`

Therefore, the equation that could be used to find the height of the flagpole is
x/5 = sin 50
