Answer:
y = 40
Step-by-step explanation:
The sum of the angles of a triangle are 180 degrees
y+10 + 2y +50 = 180
3y+60 = 180
Subtract 60 from each side
3y+60-60 = 180-60
3y = 120
Divide each side by 3
3y/3 = 120/3
y = 40
To find this, use an equation with x to represent the smaller page number as your variable. set up the equation x(x+1) = 600. distribute the x to get x^2 + x = 600. subtract 600 from both sides so you have x^2 + x - 600 = 0. factor to get (x+24)*(x+25) = 0. so the two pages are 24 and 25
