The sum of the measures of the angles of a triangle is 180. The sum of the measures of the second and third angle is two times the measure of the first angle. The third angle is 14 more than the second. Let X, Y AND Z represent the measure of the first second and third angles

X= 180 Y= 360 Z= 374

Step-by-step explanation:

180*2=360

360+14=374

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.
