Dr. black is 6 feet tall and is standing 25 feet from a streetlamp. he estimates that the angle of elevation from his line of sight to the top of the streetlamp is 20 degrees. the streetlamp is about feet tall. round your answer to the nearest foot. will give 50 points to correct answer

what i would say the best answer is a. 40.5

option c) graph of line going through 1, 4 and 3, 10

step-by-step explanation:

let y equal to margo's coin collection

let x equal to number of years

at the begining x=0, y=1 → point=(x,y)→point=(0,1)

she adds 3 coins per year, then y=1+3x

at x=1, y=1+3(1)=1+3→y=4→point=(x,y)→point=(1,4)

at x=3, y=1+3(3)=1+9→y=10→point=(x,y)→point=(3,10)

the graph of line going through (1, 4) and (3, 10), then the option c is the correct.
