Answer:
angle a = 104 degrees, angle b = angle c = 123 degrees
Step-by-step explanation:
angle c = 180 - 57
angle c = 123 degrees
angle a = 180 - 76
angle a = 104 degrees
angle b = 180 - 57
angle b = 123 degrees
Answer:
Present age of son = 15 years
& Present age of father = 40 years
Step-by-step explanation:
- Let the son's present age be x years
- -> Father's present age = (x + 25) years
- 10 years ago:
- Son's age = (x - 10) years
- Father's age = (x +25 -10) = (x +15) years
- It is given that: 10 years ago father was six times as old as his son
- -> Present age of son = 15 years
- & Present age of father = 40 years.
