Answer:
Sam: 9, Amy: 13
Step-by-step explanation:
So five years ago, lets say Sam was 4, and Amy was 8. That would be half Amy's age. If we add on 5 to Sams age, as it says, Amy would then be 13, and Sam would be 9. This is also four years apart. Thus, the answers are Sam: 9 and Amy: 13
Let's say that x is sam's age and y is Amy's age
x=y-4
and five years ago:
x-5=(y-5)/2
y-4-5=(y-5)/2
2y-18=y-5
y=13
x=9
then:
sam's age is 9 and Amy's age is 13

The triangle ABC is a isosceles so angle A = angle C
The sum of interior angles in a triangle is = 180°
74 + 74 + angle B = 180
B = 32°
