The average height of 12 Weeping Higan cherry trees planted in Washington, D. C. can be modeled by H(t) = 6.186 + 6.475 In (t), where t is the age of the tree in years. At the time of planting, the trees
were one year old and were all 6 feet in height. (
What is the average height of the trees at 7 years of age? (Round your answer to the nearest tenth of a
foot.)

call the larger triangle abc

then the smaller triangle cde is similar to abc (all angles are equal, aaa).  

ab is the side that is 36, and we wish to find de, the side corresponding to ab

area_cde = area_abc - area_cde --> area_abc / area_cde = 2

let x=length of de

ratio of areas = (ratio of sides)^2

step-by-step explanation :

we know that

the measurement of the outer angle is the semi-difference of the arcs which comprises

in this problem

m< xzy is the outer angle

substitute the values

the measure of angle xoy is equal to

> by central angle

substitute the value
