Let's assume
Raj's age is x years
Zia's age is y years
we are given
Raj is three years older than zia
so, we get

now, we can solve for y

the sum of the squares of their ages is 369
so, we get

now, we can plug back y

now, we can solve for x





Since, age can not be negative
so, we will only consider positive

now, we can find y-value


So,
Raj's age is 15 years
Zia's age is 12 years...........Answer

Answer:
The leg is 8 cm long
Step-by-step explanation:
An isosceles right triangle has the length of its hypotenuse and opposite equal
Let us call the length x
From Pythagoras’ , the square of the hypotenuse equals the sum of the squares of the two other sides
Thus, we have ;
x^2 + x^2 = (8 √2)^2
2x^2 = 128
x^2 = 128/2
x^2 = 64
x= √64
x = 8 cm
