You are standing near a pear tree you estimate to be 20 ft toll. If you are about 50 ft away, what is the angle of elevation?

mine tree heights by measuring vertical angles ... To figure out where different stands are in your forest, ... can estimate acreage within 1−2 tenths of an acre. ... example, if you had a 50-acre stand, this would mean a ... represent 20 trees per acre (TPA) in the larger stand. ... For trees that are tall enough such that 100 feet.

step-by-step explanation:

the original amount doesn't ''re just looking for the time it takes for 1/2 of the substance to we have

(1/2) =)     take the ln   of both sides

ln (1/2)   = )   and we can write

ln(1/2) = ) lne     and lne   = 1     so we have

ln(1/2) = -.1092t     divide both sides by -.1092

t = ln(1/2)/-.1092 = about 6.347 days = about 6.3 days (rounded)
