Answer:
Step-by-step explanation:
Corresponding Angles are <em>congruent</em>, therefore you set both angle measures equal to each other:
![\displaystyle 135° = [3x + 15]° → 120 = 3x; 40 = x](https://tex.z-dn.net/?f=%5Cdisplaystyle%20135%C2%B0%20%3D%20%5B3x%20%2B%2015%5D%C2%B0%20%E2%86%92%20120%20%3D%203x%3B%2040%20%3D%20x)

Answer:
11.4 years
Step-by-step explanation:
We assume you want to know the time it takes for Lucy's investment of $1200 to have a value of $6400. The compound interest formula is good for finding that.
FV = P(1 +r/n)^(nt)
for principal P invested at rate r per year for t years, compounded n times per year. We want to find t such that ...
6400 = 1200(1 +0.15/4)^(4t)
16/3 = 1.0375^(4t) . . . . divide by 1200
log(16/3) = 4t·log(1.0375) . . . . take logarithms
t = log(16/3)/(4·log(1.0375)) ≈ 11.4
It will take about 11.4 years for Lucy's investment value to be $6400.
