Apole that is 2.5m tall casts a shadow that is 1.68m long. at the same time, a nearby building casts a shadow that is 48.5m long. how tall is the building? round your answer to the nearest meter.

2.5:1.68
2.5/1.68=1.4880952381
1.4880952381:1
1.4880952381*48.5=72.1726190476
72.1726190476:48.5
Rounded, the height of the building is 72m

Hope this helps :)

False because how does that work?

Intersecting secant-tangent theorem states that if a tangent segment and a secant segment are drawn to a circle from an exterior point, then the square of the measure of the tangent segment is equal to the product of the measures of the secant segment and its external secant segment.so to break it down: 1. pq acts as the tangent and ps as the secant with an intersection at p.sr = 21rp = 3x + 3pq = 4x + 4following to equation: tangent squared = the two segments multiplied by each otherso (4x + 4) ^ 2 = (3x + 3) • (21) simplifies to 16x^2 - 31x - 47 = 0 or (16x - 47)(x + 1) x = -1 or x = 47/162. pq acts as the tangent and ps as the secant with an intersection at p (again! )sr = 16rp = xpq = 15(15) ^ 2 = 16 • x225 = 16xx = 225/163. the interesting chords are proportional to each other so a ratio is possible to set up: ap dp 10 3 + x = = —— = pc pb 8 xcross multiple to get 10x = (3 + x)(8)x = 12
