Question

a 5m 60cm high vertical pole casts a shadow 3m20cm long.find the length of the shadow cast by another pole 10m 50cm high at the same time​

Answer 1

here height is 5.6m and shadow is 3.2m

tan theta =5.6/3.2

= 7/4..... (1)

another pole height = 10.5m casts

shadow x m

tan theta = 10.5/x..... (2)

since the time is same .........

(1) and (2) are equal 10.5/x=7/4

1.5/x=1/4

x=6m
