Answer:
50 questions x 10 points = 500 points
500 points x 2 years = <u>1000 points</u>
365 days / 2 = 182 1/2 days
182 1/2 days x 2 years = <u>365 days</u>
answer. X=50
as..
draw a imaginary line between M
let it one side be y and z
y+z=120
now,
y=70(being alternate angle)
y+z =120
so
z=120-70
z=50
as we know,
z is alternate to X
so ,X=50
I think you forgot to mention Susan's current age if not:
x+5
x-4
