Mary plans to save $1000 each summer to buy a used car at the end of the fourth summer. At the end of each summer, she will deposit
the $1000 she earned from her summer job into her bank account. The table
shows the value of her deposits over the four year period. In the table, gis the
growth factor 1 + r where r is the annual interest rate expressed as a decimal.

answer: i'm not going to give you the answer, but some hints to work it out.

step-by-step explanation: so, if there is a straight line that means that the line angle is 180°. so we subtract the 2 angle measures provided, (15 and 38) from 180. so the answer is 180 - (38 + 15). (you have to solve the equation)

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
