Question

Find X in the following figure...

Answer 1

Answer:

Step-by-step explanation:

Angle of elivation =angle of deviation

Angle 30°=angle between x and 5√3

So cos 30°=b/h

√3/2=5√3/h

So by cross mutiplying

h√3=10√3

h=10√3/√3

h=10....…...ans

Answer 2

Answer:

adjside/hypo = cosx

cos30=v3/2

here 5 v3/x = cos30=v3/2

5 v3/x =v3/2

xv3=5 v3x2

x =5 v3x2/v3=10. Ans
