Answer:
x = 60
largest angle = 80°
Step-by-step explanation:
the sum of all three angles in a triangle = 180°
(3x - 100) + (x - 10) + (x - 10) = 180
simplify:
5x = 300
x = 60
angles are 80°, 50°, and 50°

Answer:
40 years old
16 years old
Step-by-step explanation:
Son = 8 years old
his father is five times as old.
Father = 5 × 8
= 40 years
How old will the father be when he will be twice as old as his son?
Father = 2 × 8
= 16 years
Father:
Five times as old as son = 40 years old
Twice as old as his son = 16 years old
