They both have the same tangent ratio so let the flagpole be x:

x/60 = 18/24

Multiply both sides by 60:

x = 1080/24

x = 45 feet

### When the shadow of a flagpole is 31.2m long a 1.6m fencepost casts a shadow 2.6m long how tall is the flagpole?

First, find the ratio of fencepost-height : shadow which is 1.6 : 2.6 . This can also be written as a fraction, 1.6/2.6 . Then, multiply the flagpole's shadow by this ratio: 31.2 x 1.6/2.6 = 19.2 The flagpole is 19.2m high. The trigonometry way: On the imaginary right angled triangle formed by the fencepost and its shadow, let the angle at which the hypotenuse meets the ground = &theta; sin&theta; = 1.6/2.6 sin&theta; = /31.2 x/31.2 = 1.6/2.6 2.6x = 31.2 * 1.6 = 49.92 x = 19.2 The flagpole is 19.2m high.

### Blake is standing next to a flagpole that is 65 feet high Blake who is 5 feet 10 inches tall is casting a shadow that is 20 feet 6 inches long Approximately how long is the shadow of the flagpole?

Let the length of the shadow be x and change all the feet into inches to avoid fractions. 780/x = 70/246 Multiply both sides by x: 780 = 70x/246 Multiply both sides by 246: 191880 = 70x Divide both sides by 70: x = 2741.142857 inches and when divided by 12 = 228.4285571 feet So the length of the shadow is about 228 feet.
