Please help! Find the measure of angle x!

(there should be a picture)

Possible Answers:

A. 15 degrees

B. 14 degrees

C. 25 degrees

D. 5 degrees

If someone explains how to find it I will give you brainliest! :)

step-by-step explanation:

try remembering the steps

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.
