Rbrberbrb
Let the present age of student be x
Present of teacher will be 4x
After 20 years,
Age of student = x + 20
Age of teacher = 4x + 20
According to the given condition after 20 years,
x + 20 = (4x + 20)/2
x + 20 = 2x + 10
2x - x = 20 - 10
x = 10
So student's present age is 10 years while teacher's is 4 x 10 i.e 40 years.

Answer:
x + 3 + 45° = 180°. isosceles triangle
x = 180° - 45°-3°
x = 132°
90° + x = 180°
x =180° - 90°
x = 90°
